Description

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, these heads are patterned after the 1969 -70 Ram Air IV Pontiac cylinder head. Two styles are available: a street legal 87cc combustion chamber version for low compression applications using 92 actane fuel and a 72cc chamber version for higher compression, racing applications. Both heads have Ram Air IV exhaust port flanges.

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 87cc BPI heads have CNC machined chambers and the pushrod holes are slotted for 1.65 rockers, included in the price. 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 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.

Sand Metal Casting, Core Production, Pattern Making, Heat Treating, Engineering, and Machining all in house, Made in the USA
Choice of CNC Machined Combustion Chamber, Hand Polished, or casted chamber* on select BP and BP Ported Heads
Don't miss the details- Heli-Coiled Bolt Holes

Heli-Coil inserts in rocker stud holes to protect threads during torquing.
Heli-Coil inserts in exhaust bolt holes to protect the threads while installing and removing headers

Intakes

340cfm heads require intakes with enough port height to be port matched. The 340cfm head requires the Edelbrock 2957/29575, NW4150, NW4500, or sheet metal.
