GM Performance Cylinder Head

Cylinder Head; Splayed Valve Race Cylinder Head; Bare; Aluminum; Splayed Ports; Single

MPN: 88958684

GM Performance Parts Splayed-Valve Aluminum Race Cylinder Heads are extremely aggressive, all-out competition heads and not intended for street use. Splayed valves point both intake and exhaust valves at the center of the cylinder bore. As the valves open, they move away from the edges of the bore. That allows maximum size valves to be installed without increasing bore size. The result is dramatically increased airflow, compared to inline valve design cylinder heads.
