To create the 5.000 Hemi performance cylinder head, MBE pulled together lessons learned from its winning NHRA and IHRA Pro Stock programs along with its 18 record-holding Comp Eliminator customers to develop ports that are perfectly sized to both maximize airflow and port velocity. This head was originally developed specifically for noted drag racer Stephen Boone to be raced in the IHRA Pro Stock class, but it will work with all big block Hemi’s with 5.000-inch bore spacing. The precisely designed ports flow an astounding 700 cfm through the intakes and 450 out of the exhausts. This is not a misprint! 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.

To get to this incredible level of performance, MBE had to make changes to everything from the valve sizes, to the port locations, to the shape of the combustion chambers, but this is what was required to finally make the absolute best power for this engine package. And the advancements are substantial all the way across the board.
