Description
Butler Performance's CNC wide port Edelbrock heads are some of the best flowing and most proven Pontiac heads available today. These heads have completely CNC ported intake and exhaust runners, so they are much more consistent port to port and head to head than many other "high flow" Pontiac cylinder heads on the market. After much time spent on design and flow testing, Butler Performance has determined that CNC porting provides a far superior cylinder head when removing the amount of material required to achieve these flow numbers.
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.
