When creating our new valve line we set out to create the best performing, longest lasting valves available to the Aftermarket. Using advanced 3D design simulation and software, we have created a stronger and greater flow valve head design. We prototype flow test valve heads in specific application flow to ensure we have the highest valve heads available on the market today. With the materials used we have tested less distortion on the valve face than any of the designs. Allows less distortion or better sealing under extreme conditions and more consistent performance over valve life. GSC Power-Division Industries' new valves are sure to become the standard for compact sport performance valves.
