If you are a drag racer running a small block, MBE’s 13 degree GB head offers the most bang for the buck you will find anywhere. This head will outperform any SB2 Cup-style cylinder head. Need proof? How about a documented 950 horsepower with these cylinder heads running a single carburetor and a cast manifold?
The secret is a CNC porting program that completely reworks these castings. MBE doesn’t mass produce cylinder heads. Instead, it concentrates on producing highly efficient heads for top-level competition, and the result is precision far beyond what you will find anywhere else. For example, in order to match more engine packages, MBE has designed three distinct port profiles for the 13 degree GB head, and the largest works with engines up to 450 cubic inches.
