The BB-2 X head works well with a light car or large engine (509-555 cu in). It has a 340 cc intake

port and flows over 360 cfm with only the bowls blended and the intake ports matched to the

gasket. The BB-2 X may be purchased angle milled to 110 cc or angle machined to 98 cc. 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. The

BB-3 works well on a 540-605 cu in engine. It has a 370 cc intake port and flows over 370

cfm, but may not be angle machined. 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 flows within 1% of each other and is 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.
