    Small Efficient Combustion Chambers!
    12°/4° Intake & 6°/4° Exhaust Valve Angles

    The Man Eater PB 1200 series takes the big block world to the next plateau! This head comes equipped with several features that include: 12° valve angle; raised, oval-shaped intake ports designed to achieve a delicate balance between horsepower and torque; and precision contoured shallow chambers with outstanding wet flow characteristics. The new BP PB 1204 series features raised 510cc intake ports that flow over 570 cfm and exhaust ports that flow over 350 cfm! The PB 1203 series is the latest in as-cast technology. It is the most powerful out-of-the-box head in its class. The PB 1202 series takes the Man Eater PB 1200 series a step further. This head features 497cc oval-shaped intake ports that are raised an additional .125'' and utilizes a 2.520'' intake valve. The Man Eater BP PB 1200/1201/1202/1204 series are 100% CNC ported while the PB 1203 series are intake port matched with bowls blended, complete valve job and CNC'd combustion chambers while the intake/exhaust ports are as-cast. The standard features are A-356 virgin aluminum alloy, phosphorous bronze valve guides, and copper valve seats. These heads are machined to accept 1.740'' valve spring cups and can be used in conjunction with the Brodix PM series of intake manifolds.
    PB 1200 series heads require special pistons, valve covers, head studs, shaft mounted rocker arms, and intake manifold.
    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 copper valve seats installed.
