Details
MBE created the 24 Degree Conventional GM-style cylinder head specifically for Super Stock drag racers and anyone else in similar classes. By very carefully refining the ports and other critical dimensions on this head, MBE has created a race head that flows an incredible 390 cfm through the intake ports and 286 out the exhausts while still maintaining the proper port volumes and valve sizes to keep it legal for Super Stock racing.
The secret that sets this head apart from the competition is a unique port design practically equalizes flow between all the intake ports. Typically, this head suffers from unequal amounts of flow through the intake ports which makes it difficult to properly tune the air/fuel ratios and hurts overall power.

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.
