The BB-2 XTRA head works well on a 540 cu in or larger engine. It has a 365 cc intake port and flows over 375 cfm with only the bowls blended and the intake ports matched to the gasket.

While creating the BB-2 XTRA CNC, the professionals at BRODIX invested many long hours on the flow bench and at the track developing a completely ported cylinder head. BRODIX incorporated this porting design into a 100% CNC ported masterpiece that can be mass produced. One of the most accurate, best flowing out-of-the-box cylinder heads is now available. Each of the castings flow within 1% of each other and are CNC ported to a mirror finish. The bottom line is that our customers can now buy the best casting with the best CNC porting 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. Valve cover rails are now raised to assure no oil leakage.
