This is the 18 degree small block head that destroys all the boundaries for this style cylinder head. In order to maximize its design MBE uses its own casting to create a race-ready cylinder head that flows an unmatched 400 cfm through the intake ports. That’s an unheard of number for an 18 degree head, but MBE backs that up with the only guarantee in the industry that your flow bench testing will meet or exceed its advertised flow numbers.
Because it controls both the design and the casting, MBE has defied convention by making the most powerful 18 degree head on the market also one of the most economical. Racers used to paying a premium price for class-leading horsepower are constantly surprised by the value of this ultra-competitive race head.
