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.
