    These 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 feature a center water outlet for improved cooling and interlinked rocker stud pad with extra thread engagement for improved valvetrain stability. Finally, they feature raised valve cover rails and spring pads to compliment the improved port design, but still retain the stock bolt pattern.

    Victor Pro-Port Raw head p/n 350-77819 features 5/8'' raised intake ports and the intake flange has also been extended 5/8'', will fit stock manifolds. Victor Pro-Port Raw head p/n 350-77829 features a 1.25'' raised intake ports and flange. Made In The USA!
