Technical Notes: Performer RPM 460 heads accept factory exhaust, aftermarket headers and factory valvetrain components. Requires the use of 3/8" diameter pushrods. Match with Edelbrock head gasket sets on pages 126-128. Bare heads will have valve guides and seats installed, but will require final sizing and 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. |
