    Performer Pontiac heads utilize a D-Port exhaust port configuration for use with standard D-port exhaust systems. They are designed for 1962-79 389, 400, 421, 428 and 455 cid V8 Pontiac engines with a 4.060' or larger bore. They feature optimized oil return passages for increased oil flow. These heads are available in three heart shaped combustion chamber sizes, including 65cc, 72cc and 87cc. The 65cc combustion chambers are as-cast while the 72cc and 87cc 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.

    Technical Notes: 350 c.i.d. engines may require notching the block for valve clearance. Three head bolt bosses are raised higher than the standard D-port heights and will require head bolt kit p/n 350-8561 to install these heads.

    Edelbrock Performer Pontiac D-Port Aluminum Cylinder Heads deliver substantial performance upgrades while offering ease of installation for Pontiac V-8 enthusiasts. Designed specifically for 1962–79 Pontiac engines—including 389, 400, 421, 428, and 455 ci displacements—these heads are crafted from lightweight aluminum to enhance engine response and improve front-end weight balance.

    Featuring a D-Port exhaust design that works seamlessly with factory-style exhaust systems, these heads come with reliable enhancements such as optimized oil return passages, relocated spark plugs nearer the exhaust valve for more efficient combustion, and reinforced port walls—perfect for both CNC and hand porting.

    Available in combustion chamber sizes of 65cc, 72cc, and 87cc—each engineered for improved compression with flat-top pistons—these heads support performance gains in horsepower and torque. As aluminum components, they help reduce underhood temperatures and enable quicker warm-up times, contributing to improved throttle feel and consistent performance across daily driving or spirited builds.

    Installation is straightforward, with these heads provided complete with guide plates, rocker studs, and a high-quality valvetrain assembly—offering true bolt-on simplicity.

    Whether you're improving engine breathing or refreshing a driver, these aluminum pontiac heads give your ride lasting durability and performance.
