    Description

    BPI-11 DEGREE PRO PORT HEADS
    (Extensive Wet Flow Testing & Development)

    These new heads are the ultimate choice for extreme Pontiac race applications. They feature raised intake port openings and extended intake flanges for improved flow, while retaining the stock location, making them compatible with Victor series manifolds and Ram Air IV style headers. The intake valves have also been moved away from the cylinder wall allowing for improved burn characteristics when used with larger than stock diameter valves. These heads also features a center water outlet for improved cooling and interlinked rocker stud pad with extra thread engagement for improved valve train stability. Finally, they feature raised valve cover rails and spring pads to compliment the improved port design, but still retain the stock bolt pattern.
