MBE has two Pro Stock cylinder head offerings for Ford racers that are complete clean-sheet designs and feature the latest discoveries from MBE’s ongoing R&D programs to aid port flow and increase the rate of burn inside the combustion chambers.
MBE offers two versions of the NHRA-legal Pro Stock heads--a small port and a large part--and both are proven race winners. In order to perfect each design for the application, they are also cut for different valve sizes and angles. The large port head design works with cylinder blocks that have 4.900-inch bore spacing and features slightly larger intake ports that flow an astounding 625 cfm through the intakes and 355 out the exhausts.
