The BB-2 heads work well with a heavy car and smaller engine (427-509 cu in). The BB-2 has a 305 cc intake port and flows 320 cfm.

These heads may be purchased angle milled to 110 cc. The combustion chambers are 119 cc and are properly shaped for use with either methanol or gasoline, preventing detonation.

The bottom line is that our customers can now buy the most accurate, best flowing out-of-the-box cylinder heads available at the best price. These cylinder heads accept all standard pistons, intake manifolds, and rocker arms. The exhaust ports are raised .600 higher than stock, and the valve cover rails are now raised to assure no oil leakage.
