This is the cylinder head that is currently dominating Northeast Modified Big Block racing. Winning drivers such as Billy Decker, Paul Ward and Dale Plank depend on MBE’s 18 Degree Conventional head for their engine programs, and the results speak for themselves. At the 2010 Syracuse Super Dirt Week, MBE’s 18 Degree heads were on cars that finished first and second in qualifying. But that’s not surprising, in seven of the last nine years the driver that produced the quickest lap time at Syracuse has depended on MBE power.
The secret that sets this head apart from the competition is a unique port design that 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. This even includes custom port work on intake manifolds to make sure the entire induction path is optimized for the engine. It’s all a part of MBE’s commitment to you: Power through precision.
