Installation Notes
  • Match with Edelbrock head gasket sets. 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. To use stock rockers on small-block Chevy heads, .100" longer than stock pushrods are required. Edelbrock pushrods #9629 recommended. Use Head Bolt Kits for easy installation. Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat. This head does not include valve springs due to the wide variety of camshafts used in competition. Please consult your camshaft manufacturer for appropriate valve spring selection. Deck thickness: 9/16", rocker stud diameter: 3/8", pushrod diameter: 5/16" (width of slot in guide plate).
