INSTALLATION NOTE: Bare heads will have valve guides & seats installed, but will require final sizing & a valve job to match the valves you will be using. Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat. All Performer and Performer RPM Big-Block Chevy heads: Spark plug is closer to center of bore, will interfere with high-dome pistons for open chamber heads. Use pistons designed for our heads. Match with Edelbrock head gasket sets.
