Edelbrock part #41623 Classic Series Valve Covers are designed for Ford FE V8 1958-1976 applications. Edelbrock first made these aluminum valve covers in the late '50s and they're still a classic. Made of heavy-gauge sand-cast aluminum with a Black powder coat finish. Overall height is measured from base to top at the highest point. Edelbrock classic valve covers can be machined to accept breathers if desired. May not clear some power brake boosters on Ford FE applications.
