Edelbrock Performer Series aluminum cylinder heads are specifically designed for performance street use. These heads are 50-state legal and provide excellent bolt-on performance for 1965-95 289, 302 & 351-Windsor engines. The performer aluminum heads are available with either 1.90" or 2.02" intake valves. The 1.90" intake valves are for use with Stock Pistons, while the 2.02" intake valves are for use with pistons that are notched for valve clearance. Sold individually, two per engine required.
Note: Hardened pushrods are required (350-9632 flat tapped only). These heads will NOT accept rail rockers. Ford 289-302 engines require the use of head bolt bushings (350-9680).
All bare heads come with valve guides and seats installed, but these heads will require final sizing and a valve job to match the valves being used.
