We make them KICK A__!!!! with these valves!
With these valves, our competition valve job, cams, flowing and port work, we are seeing an honest, almost 50 horsepower gain and 50 torque. (nearly 200 with stock exhaust manifold) RET Racing Engine Technologies www.facebook.com/RacingEngineTechnologies
