    Note: These heads are sold bare and will require proper machining of the valve guides and a finish valve job for the specific valves the customer chooses to install. These heads require offset rocker arms for the intake ports and the exhaust side will accept standard-spec rockers. May require additional pushrod hole clearance for some combinations. Will need to use Edelbrock Valley plate kit 350-7798 for RB engines and 350-7799 for B engines.
