  • When creating their new valve line they set out to create the best performance longest lasting valves available to the aftermarket. Using advanced 3D design and simulation programs they have created a stronger and higher flowing valve head design. They flow test prototype valve heads in the specific applications to make sure they have the highest flowing valve head available on the market today. With the materials used they have less valve distortion at the face than any of the tested designs. Less distortion allows or better sealing under extreme conditions and more consistent performance threw the life of the valve. GSC Power-Division's new valves are sure to become the industries standard for sport compact performance valves.

  • BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel material to insure reliability with high boost and/or high rpm 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.

  • Manley Performance is universally acknowledged as the leading manufacturer of performance and racing valves in the world. The reason for Manley’s overwhelming success is simple: QUALITY. We offer the best materials in the industry-exclusive materials our competitors do not possess. Our stems are hard coated with .0002" thick chrome rather than a few millionths of flash. Our hard tips are superior to competitors’ puddled satellites which can crack and erode off the stem. Our valve head and under head shapes have been at the forefront of the quest for improved flow since the late 1960s. And always each Manley valve has been price targeted to specific markets to ensure the best possible value to the customer.
