These heads are an all new design that utilizes the D-Port exhaust port configuration for use with standard D-Port aftermarket exhaust systems. Performer Pontiac heads are designed for Pontiac engines with a 4.060 Inch or larger bore. Manufactured with optimized oil return passages for increased oil flow. The casting is manufactured from A356 aluminum and heat treated to T6 specification for superior quality. These heads are available in three dual quench combustion chamber sizes, including 65 Cubic Centimeters, 72 Cubic Centimeters, and 87 Cubic Centimeters. The 65 Cubic Centimeters combustion chambers are As-Cast while the 72 Cubic Centimeters and 87 Cubic Centimeters chambers are fully CNC’d to provide a 9.5:1 compression ratio when used with flat top pistons. The spark plug has been relocated closer to the exhaust valve for improved performance. These heads are cast with extra thick port walls and a compact port size, making them ideal for CNC and hand porting. Complete heads include guide plates, rocker studs and high quality valvetrain for direct Bolt-On application. Heat crossover is machined for 50 state emissions legal performance
