    Moved Valve Centerlines and Flows 370 CFM!
    13° Intake & Exhaust Valve Angles

    With the introduction of the new BP -13, Brodix adds yet another weapon to its arsenal of cutting edge cylinder heads. Due to the use of their unique ''Total Control'' process, the BP -13 is unmatched in both quality and performance. It utilizes a 13° valve angle, moved valve centerlines, and a 47cc wet flow friendly combustion chamber. The 100% CNC ported offering from Brodix is destined to become the industry standard. This head has special valve centerlines and dowel location requiring special components. Interlocking valve seats are installed along with replaceable phosphorous bronze guides. The -13 series has two exhaust bolt patterns available and a 5° intake face requiring a special intake manifold and components (compatible with 18° intakes/headers). 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 interlocking valve seats.
