BC Inconel valves are intended for high boost, high horsepower applications.
The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber.
Every valve is fully machined and features a swirl polished finish under the head.
