Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.

Designed for 400, 430 and 455ci Buick engines, these Performer RPM cylinder heads are available fully assembled and ready to bolt on or bare for use with your own valve train components. Features include high-quality stainless steel 2.125" intake and 1.75" exhaust valves, 68cc combustion chambers and high flow 215cc intake and 130cc exhaust ports. Intake and exhaust runners are hand blended in the bowl area and the intake entries and exhaust exits are CNC profiled for increased air-flow. These heads include adjustable rocker stud and guide plate set-up for use with small-block Chevy 1.6:1 style adjustable rockers. The casting is manufactured of A356 aluminum and heat treated to T6 spec for superior quality. An extra-thick 5/8" deck and Heli-coil threaded inserts offer improved durability. Made In The USA!
