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 PB 1203 is the latest in

as-cast technology. It is the most powerful out-of-the-box head in its class. The PB 1202 takes

the Man Eater PB 1200 series a step further. This head features 497 cc oval-shaped intake

ports that are raised an additional .125 and utilizes a 2.520 intake valve. The Man Eater PB 1200

series is available 100% CNC ported to ensure accuracy. 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 manifolds.
