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.
