High Performance Valves

These high performance valves are one piece forged stainless steel. Featuring hard chromed 11/32" stems. In addition to their heavy duty features, the design will increase air flow capabilities. Resulting in increased horsepower. The oversize exhaust valve will show a substantial performance gain in high performance applications. Both intake and exhaust will work with stock type keepers and retainers (although our #14-264 keeper set is recommended for all performance applications). All valves are sold per each. For information on valve setting stem heights, see our Tech Section
