Details
To create the 12 Degree Big Duke 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.
With 2.500-inch intake valves and 1.860-inch exhaust valves installed in combustion chambers than can be sized anywhere between 68 and 78 cc’s, the precisely designed ports flow an astounding 560 cfm through the intake and 354 out of the exhausts. 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.

is the leading induction specialists in the country, with cylinder heads and intake manifolds used in championship winning programs from NASCAR Nextel Cup, to NHRA Pro Stock, to Sprint Cars to Dirt Late Models and more. MBE is the only CNC porting company to guarantee cfm flow numbers for every cylinder head it produces—and those numbers are often the highest you will see anywhere. MBE maintains an aggressive R&D program and constantly updates its cylinder head and intake profiles to stay ahead of the competition.
In racing, there is no “one size fits all” solution, so MBE custom fits port and chamber designs specifically to each racer’s application.
