    Proven Competition Head That Works with
    Most Standard Big-Block Chevy Components!

    26°/4° Intake & 17°/4° Exhaust Valve Angles

    The BB-2 X head works well with a light car or large engine (509-555ci). It has a 340cc intake port and flows over 360 cfm with only the bowls blended and the intake ports matched to the gasket. Available with a 110cc, 115cc or 119cc combustion chamber, but may be angle machined to 98cc. The BB-2 X features a CNC'd intake port match and bowls are blended while the intake ports, exhaust ports and combustion chambers remain as casted.
    The BB-2 XTRA head works well on a 540ci or larger engine. It has a 365cc 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 540-605ci engine. It has an exhaust valve centerline that is moved by .300'' with a 370cc intake port and flows over 370 cfm, but may not be angle machined. While creating the 100% CNC Ported BP series BB-2 XTRA, 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 ported masterpiece that can be mass produced. The BP BB-2 XTRA heads are CNC-ported to a mirror finish and flow within 1% of each other. The bottom line is that Brodix builds you 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. Valve cover rails are now raised to assure no oil leakage. Every casting is poured from A-356 virgin aluminum and tested before Brodix utilizes their in-house processes such as finish machining and heat treating to assure that you receive the best products for your hard-earned money. Other features include a thick deck surface that is compatible with nitrous, drilled and tapped holes on the ends for standard drive accessories, phosphorous bronze valve guides and hardened valve seats installed for unleaded fuel. Sold Individually, 1/pkg. Made in the USA!
