Butler Performance Inc. - Wide Port Cylinder CNC Heads
Butler Performance's CNC wide port Edelbrock heads are some of the best flowing 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 any other "wide port" or "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.
