Technical Notes: The special valvetrain in the 1970 340 T/A is not compatible with these heads. Match with Edelbrock head gasket sets. Bare heads will have valve guides & 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. |
