Details
MBE has two Pro Stock cylinder head offerings for Dodge 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 also have different, specific valve sizes and angles. The small port head is specifically designed to make the best power in engines between 430 and 460 cubic inches, but just because we call this a small port head don’t make the mistake that it also means small amounts of flow. In fact, it’s just the opposite.
