MBE’s Pro Stock cylinder head offerings are complete clean-sheet designs that 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 three versions of the NHRA-legal Pro Stock heads (DRCE I, II and III) and all are proven race winners. They work with cylinder blocks that have 4.900-inch bore spacing and boast an incredible 625 cfm flow through the ports. And remember, MBE is the only induction specialist willing to stand behind its advertised flow numbers with a guarantee that you will see the same or better performance on your own flow bench.
