AFR's 220cc "Race Ready" and "Competition" heads feature 100% CNC ported intake, exhaust & chambers, A356 aluminum castings and high quality components throughout. This is AFR's largest, best flowing head for use with conventional rocker arms. Recommended for race applications or radical "Pro Street" style builds.
Notes: Race ready porting. Cylinder heads are based on L98 geometry, not compatible with self-aligning rocker arms. Exhaust port is raised 0.250 in. over stock.
