With 211/177 Valves

Edelbrock Performer RPM heads produce outstanding horsepower with excellent low-speed torque and throttle response. Designed for 1965-79 389-455 c.i.d. Pontiac engines. Two styles are available: a street legal 87cc combustion chamber version for low compression applications using 92 octane fuel and a 72cc chamber version for higher compression, racing applications.

**Now available in 65cc***

BP has conducted extensive flow bench, dyno, and track testing with these heads, all resulting in great performance numbers. We have cylinder head packages for any application, from 7-second racecars to 8 & 9-second street cars and even daily drivers. Call for a cylinder head combo to fit your needs.

All BPI heads have polished chambers and the pushrod holes are slotted for 1.65 rockers, included in the prices. All these heads use standard valve train components.

All BPI Edelbrock in-stock heads can be upgraded with roller springs, titanium retainers, milling, o-ringed, etc. for an additional price. Or, you may send your Edelbrock heads to BPI to be ported and upgraded for improved performance.

Additional Options available such as custom matched paint or logo removal

Why Edelbrock Castings?
Butler has had the opportunity over the years to have our own brand castings. The decision was easy for us. Due to the amount of metallurgy expertise needed and inconsistencies in foundries, we chose THE experts in the industry that stay on top quality and consistency. They have proven this through years in the performance aftermarket cylinder head and intake business. Here are a few reasons why the Edelbrock casting, Butler Process machining, high quality parts, and expert blueprinting and assembly, there is no other head on the market that comes close.
