If your engine has suffered a catastrophic failure which requires replacement of your cylinder heads, or if you don't have OEM heads to start with, the IAG 550 Cylinder Heads are a perfect solution. These heads also work great for cars with basic bolt-on parts up to 550 BHP. These heads include upgraded GSC standard size valves, GSC Viton Valve Stem Seals, IAG Stage 1 Valve Springs with Titanium Retainers, and OEM Keepers. GSC S1 Camshafts are available with OEM valve lifter buckets. We also offer an optional chamber modification service (see below) for EJ20 heads to allow use on EJ25 short blocks.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-1f7108e1-f477-4977-ac32-2c52b586b0c8\"\u003e\n\u003cdiv class=\"shg-row\" data-col-grid-mode-on=\"\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-23abdd9d-1ba5-4e24-b942-bc27b233712d\" class=\"shg-c  shg-align-center\"\u003e\n\u003cdiv class=\"shogun-heading-component\" data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInLeft\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]'\u003e\n\u003ch2\u003eBUILT WITH 100% NEW COMPONENTS\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-45dbe5e0-42f6-4efa-8697-6dc5919902c2\" class=\"shg-c\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eEach IAG 550 Cylinder Head Set starts with new OEM castings from Subaru of America. The first step is to select your Year and Model of vehicle so that we may provide you with the right castings to fit your project. Next, you'll select whether or not you want to include our optional GSC camshaft package. If selected, these heads will include new GSC S1 Camshafts and OEM Lifter Buckets for valve adjustment.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe bare castings are visually inspected and then fixtured into our in-house Centroid 5-axis CNC Machine. In the Centroid, the heads undergo a cam clearance machining process which removes material from the lifter area where larger lift and duration cam profiles are known to contact the castings. (Just in case you want to go bigger later.) Then the heads are fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of GSC's standard size 36mm Intake and 32mm Exhaust valves. At this point, the heads' decks are resurfaced using our TS-3000 BlockMate, which cuts the aluminum to a smooth, even finish. Next, the heads are ultrasonically cleaned to remove debris and oils from the machining process. Finally, the heads are reassembled using GSC Stainless Intake and Exhaust Valves, GSC Viton stem seals, IAG-Stage 1 Valve Springs with Titanium Retainers, and OEM Valve Keepers.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv class=\"shg-c shogun-image-container    shg-align-center\" id=\"s-55140fd3-be21-469a-9435-d5a48f7189e8\"\u003e\u003cimg data-src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" width=\"\" height=\"\" alt=\"Newen Seat and Guide Machine Machining IAG Cylinder Heads\" class=\"shogun-image  shogun-lazyloaded\" decoding=\"async\" src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"shg-c shogun-image-container    shg-align-center\" id=\"s-7a5c8386-3241-4d59-bb50-89da016ef8b9\"\u003e\u003cimg data-src=\"https:\/\/i.shgcdn.com\/24196a6a-7424-4e55-91e0-724e30553ed9\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" width=\"\" height=\"\" alt=\"Centroid 560A Machining IAG Subaru Cylinder Heads\" class=\"shogun-image  shogun-lazyloaded\" decoding=\"async\" src=\"https:\/\/i.shgcdn.com\/24196a6a-7424-4e55-91e0-724e30553ed9\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-4714b127-4ccf-438d-bcb7-85009f9f2750\"\u003e\n\u003cdiv class=\"shg-row\" data-col-grid-mode-on=\"\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv class=\"shg-c shogun-image-container shogun-image-lightbox-content   shg-align-center\" id=\"s-4720106f-7a96-46d3-a438-91fdaed9dd16\" data-shg-lightbox-switch=\"true\"\u003e\u003cimg data-src=\"https:\/\/i.shgcdn.com\/5bc2130c-994d-41c5-af13-59d9e35d39f5\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" width=\"\" height=\"\" alt=\"GSC Stage 1 Cams \u0026amp; OEM Lifter Buckets\" class=\"shogun-image  shogun-lazyloaded\" decoding=\"async\" data-shg-lightbox-image=\"true\" src=\"https:\/\/i.shgcdn.com\/5bc2130c-994d-41c5-af13-59d9e35d39f5\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-8cd92638-38a7-40df-bab0-d9f44e31cff4\" class=\"shg-c  shg-align-center\"\u003e\n\u003cdiv class=\"shogun-heading-component\" data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInRight\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]'\u003e\n\u003ch2\u003eOPTIONAL GSC S1 CAMSHAFT AND LIFTER BUCKET PACKAGE\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-b2182899-ff67-46a7-9971-34ec37845754\" class=\"shg-c\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eIf you're planning for more power you'll want to select these GSC Power-Division billet S1 camshafts for your IAG 550 Head Package.

These CNC pocket ported heads provide a significant upgrade in flow over the IAG 550 heads. These heads work great for cars with some race track duty (road, rally, auto-x, drag) and are designed to support up to 750 BHP with supporting mods. These heads include upgraded GSC Standard Size Valves, GSC Viton Valve Stem Seals, IAG Stage 1 Valve Springs with Titanium Retainers, and OEM Keepers. GSC S1 Camshafts are available with OEM valve lifter buckets.

The first step is to select your Year and Model of vehicle so that we may provide you with the right castings to fit your project. Next, you'll select whether or not you want to include our optional GSC camshaft package. If selected, these heads will include new GSC S1 Camshafts and OEM Lifter Buckets for valve adjustment.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe bare castings are visually inspected and then fixtured into our in-house Centroid 5-axis CNC Machine. The Centroid CNC ports the intake and exhaust runners under the valves and blends them to the valve seat. Once the Centroid completes the port process, the heads undergo a cam clearance machining process which removes material from the lifter area where larger lift and duration cam profiles are known to contact the castings. The heads are then fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of GSC's standard size valves. At this point, the heads' decks are resurfaced using our TS-3000 BlockMate, which cuts the aluminum to a smooth, even finish. Next, the heads are ultrasonically cleaned to remove debris and oils from the machining process. Finally, the heads are reassembled using IAG Stage 1 Single Valve Springs and Titanium Retainers along with GSC Viton stem seals.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-64449910-dbe2-4680-bf51-934a09b6989e\" class=\"shg-c shogun-image-container    shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"Newen Seat and Guide Machine Machining IAG 750 Cylinder Heads\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"s-bc2ee683-6bb9-4d21-a8cd-d9556c4c8888\" class=\"shg-c shogun-image-container    shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/24196a6a-7424-4e55-91e0-724e30553ed9\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"Centroid 560A Machining IAG 750 CNC Pocket Ported Subaru Cylinder Heads\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/24196a6a-7424-4e55-91e0-724e30553ed9\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-34000ff5-b999-48d8-a14b-9c4556836a26\" class=\"shg-c\"\u003e\n\u003cdiv data-col-grid-mode-on=\"\" class=\"shg-row\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv data-shg-lightbox-switch=\"true\" id=\"s-1db9d33e-b440-4878-8243-f1f1345019ff\" class=\"shg-c shogun-image-container shogun-image-lightbox-content   shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/c75893c5-fbe3-4fa8-9257-bd624d4640ba\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" data-shg-lightbox-image=\"true\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"IAG 750 CNC Pocket Port Cylinder Head\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/c75893c5-fbe3-4fa8-9257-bd624d4640ba\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv class=\"shg-c  shg-align-center\" id=\"s-6fa404c3-a3ac-4103-a52f-444b3824885c\"\u003e\n\u003cdiv data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInRight\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]' class=\"shogun-heading-component\"\u003e\n\u003ch2\u003eWHAT IS A POCKET PORT?\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-28bc7fb1-55c0-44e2-b0bf-15d5d35f3a1f\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003ePocket porting is enlarging and blending the area under the valve seat.

The rest of the port is left alone because additional volume is not required at these power levels, and can even hurt velocity if there's not enough airflow.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-1543e243-5388-4a24-9765-7366ef0569fb\" class=\"shg-c\"\u003e\n\u003cdiv data-col-grid-mode-on=\"\" class=\"shg-row\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv class=\"shg-c  shg-align-center\" id=\"s-a1376d9e-5071-4e91-904f-c916530c59c8\"\u003e\n\u003cdiv data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInLeft\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]' class=\"shogun-heading-component\"\u003e\n\u003ch2\u003eOPTIONAL GSC S1 CAMSHAFT AND LIFTER BUCKET PACKAGE\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-b9fc8c9f-a582-4a51-b86c-fee689d993aa\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eIf you're planning for more power you'll want to select these GSC Power-Division billet S1 camshafts for your IAG 750 Head Package.

Next, you'll select whether or not you want to include our optional GSC camshaft package. If selected, these heads will include new GSC S2 Camshafts and OEM Lifter Buckets for valve adjustment.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis IAG 950 fully CNC ported head package starts with brand new WRX STI OEM head castings directly from Subaru of America. The bare castings are visually inspected then fixtured into our in-house Centroid 5-axis CNC Machine. The Centroid CNC ports the intake and hard to reach exhaust \"dog-leg\" port runner. The benefit of CNC porting is not only an efficient way of machining the heads it also offers consistent port results that are hard to achieve by hand. Once the Centroid completes the port process the heads undergo a cam clearance machining process that removes material from the lifter area where large duration cam profiles are known to contact the castings. Shortly after the heads are drilled to fit larger 1\/2\" or 14mm head studs, which are commonly used in high horsepower builds. Next, the OEM guides are pressed out and replaced in favor of GSC Manganese-Bronze valve guides that are shaped to improve airflow. Once all the new intake and exhaust guides are in place they are diamond-honed in our honing station. The heads are then fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of GSC's +1mm valves. At this point, the heads' decks are resurfaced using our TS-3000 BlockMate which cuts the aluminum to a smooth even finish. Next, the heads are ultrasonically cleaned to remove debris and oils from the machining process. Finally, the heads are reassembled using IAG-Spec Beehive Valve Springs and Retainers along with GSC Viton stem seals.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-4634d57c-b1a9-4fa1-aa4d-0504b209af67\" class=\"shg-c shogun-image-container    shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"Newen Seat and Guide Machine Machining IAG 950 Cylinder Heads\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"s-cf5f6585-5ca4-49a9-8e28-c4028ecd85b8\" class=\"shg-c shogun-image-container    shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/24196a6a-7424-4e55-91e0-724e30553ed9\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"Centroid 560A Machining IAG 950 CNC Pocket Ported Subaru Cylinder Heads\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/24196a6a-7424-4e55-91e0-724e30553ed9\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-7831adcb-275b-4d17-972b-746a67412172\" class=\"shg-c\"\u003e\n\u003cdiv data-col-grid-mode-on=\"\" class=\"shg-row\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv data-shg-lightbox-switch=\"true\" id=\"s-7660426b-91c2-433f-8df6-1f81fcfaa261\" class=\"shg-c shogun-image-container shogun-image-lightbox-content   shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/5b368803-7ea7-4308-9364-8473a85efaee\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" data-shg-lightbox-image=\"true\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"IAG CNC Port CAD Model for EJ Subaru Engines\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/5b368803-7ea7-4308-9364-8473a85efaee\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv class=\"shg-c  shg-align-center\" id=\"s-394f9e90-7f34-4f80-97e8-5ff46411ddd3\"\u003e\n\u003cdiv data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInRight\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]' class=\"shogun-heading-component\"\u003e\n\u003ch2\u003eWHAT MAKES CNC PORTING BETTER?\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-a9f82107-d00c-4906-9a8b-95c9837b8d83\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eCylinder head porting has been around since the invention of the internal combustion engine. It can be done by hand with a die grinder and some cartridge rolls, and a seasoned professional can likely get a good result that way. Unfortunately, doing porting this way requires a lot of experience and care. One slip of the die grinder can ruin your cylinder head. This is where CNC porting comes in. Using our Centroid 5 axis CNC porting machine we can achieve the same results every time we put a set of heads into the machine.

The bare castings are visually inspected then fixtured into our in-house Centroid 5-axis CNC Machine. The Centroid CNC ports the intake and hard to reach exhaust \"dog-leg\" port runner. The benefit of CNC porting is not only an efficient way of machining the heads it also offers consistent port results that are hard to achieve by hand. Once the Centroid completes the port process the heads undergo a cam clearance machining process that removes material from the lifter area where large duration cam profiles are known to contact the castings. Shortly after the heads are drilled to fit larger 1\/2\" or 14mm head studs, which are commonly used in high horsepower builds. Next, the OEM guides are pressed out and replaced in favor of GSC Manganese-Bronze valve guides that are shaped to improve airflow. Once all the new intake and exhaust guides are in place they are diamond-honed in our honing station. The heads are then fixtured in our Newen Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of Ferrea's +1mm valves. At this point, the heads' decks are resurfaced using our TS-3000 BlockMate which cuts the aluminum to a smooth even finish. Next, the heads are ultrasonically cleaned to remove debris and oils from the machining process. Finally, the heads are reassembled using Ferrea Drag Springs and Retainers along with Ferrea Viton stem seals.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv id=\"s-4808b243-597d-42e0-9f7e-7e06c4371f3e\" class=\"shg-c shogun-image-container    shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"Newen Seat and Guide Machine Machining IAG 750 Cylinder Heads\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/ab285357-5f46-41b2-9201-89f35697bdd1\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"s-91a0ac1e-50ec-4506-8adf-8a82144d6626\" class=\"shg-c shogun-image-container    shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/24196a6a-7424-4e55-91e0-724e30553ed9\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"Centroid 560A Machining IAG 750 CNC Pocket Ported Subaru Cylinder Heads\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/24196a6a-7424-4e55-91e0-724e30553ed9\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"s-c8c32dbe-6eb7-40d8-9d3b-6f170101a848\" class=\"shg-c\"\u003e\n\u003cdiv data-col-grid-mode-on=\"\" class=\"shg-row\"\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv data-shg-lightbox-switch=\"true\" id=\"s-55d4333d-f558-4b16-b828-3653fb378f54\" class=\"shg-c shogun-image-container shogun-image-lightbox-content   shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/5b368803-7ea7-4308-9364-8473a85efaee\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" data-shg-lightbox-image=\"true\" decoding=\"async\" class=\"shogun-image  shogun-lazyloaded\" alt=\"\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/5b368803-7ea7-4308-9364-8473a85efaee\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c-lg-6 shg-c-md-6 shg-c-sm-6 shg-c-xs-12\"\u003e\n\u003cdiv class=\"shg-c  shg-align-center\" id=\"s-ce609745-c612-4560-a271-36b657348071\"\u003e\n\u003cdiv data-animations='[{\"event\":\"enterviewport\",\"name\":\"fadeInRight\",\"delay\":\"\",\"duration\":\"\",\"iterationCount\":\"\",\"shouldBeTriggeredOnce\":false}]' class=\"shogun-heading-component\"\u003e\n\u003ch2\u003eWHAT MAKES CNC PORTING BETTER?\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-4f1b2e51-51f1-4cc0-ad0a-b4ac8a8fa60b\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003e\u003cspan\u003eCylinder head porting has been around since the invention of the internal combustion engine.
