Description

Includes all of the features below from our popular CNC Ported Edelbrock Cylinder heads but with a new optional port design for 2026

With extensive digital modeling, CAD and CAM design, and flow testing of a newly designed port we are able to keep your RA4 intake port height and width but create 310-315cfm of flow. This allows the use of all the popular intakes that can be port matched to the RA4 port size. This is a big deal when it comes to intake heights for Shaker and hood clearances.

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 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 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
  • 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
