Technical Notes: Hardened pushrods required, use Edelbrock #9632 (flat tappet only). Will not accept rail rockers. 289-302 V8s require Head Bolt Bushings #9680 and either Head Bolt Kit #8552 (7/16") or stock head bolts. Match with Edelbrock head gasket sets. Bare heads will have valve guides and 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. |
