Technical Notes: 1986 5.0L need pistons notched for clearance. Will not accept rail rockers. 5.0L requires 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 & 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. |
