The Edelbrock 60599 Performer RPM Cylinder Head is designed to deliver strong performance gains for Pontiac 389–455 CID V8 engines. Modeled after the legendary 1969–1970 Ram Air IV cylinder head, this aluminum head improves airflow and efficiency for street and performance builds. Featuring 215cc intake runners and 2.11" intake valves, it supports power levels in the 450–550 horsepower range. This version is specifically configured for flat tappet camshaft applications, making it ideal for traditional Pontiac performance builds.
