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.
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

I own a 1974 Pontiac Trans Am 455. Back in May I decided to modify and rebuild the tired motor and it wasn't long before I settled on the Butler Performance BPI-87cc-EDL-DPort-310CNC. It took BP only a short to transport the heads to me in Australia. The dyno figures were 465 horsepower and 600 ft pounds torque..... Not too bad.
Thanks Butler Performance
