    E-205 Series Aluminum Cylinder Heads

    Technical Notes: Hardened pushrods required, use Edelbrock #9632 (flat tappet only) for 302 applications. 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.

    The E-205 cylinder head for Small Block Ford 289, 302, and 351W engines provide race-level performance while maintaining full compatibility with OEM equipment. Featuring larger runners for increased airflow with revised exhaust ports and larger diameter springs for higher lift camshafts making it ideal for a spec series racer and larger displacement engines. The exhaust port flange is in the stock location to allow for the use of off-the-shelf headers and hardware while the enlarged valves and ports support the power needed to compete at engine speeds of up to 6500 RPM. The E-205 cylinder head is capable of supporting more than 500 naturally aspirated horsepower and even more in forced induction applications. Made In The USA!
