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.
