Edelbrock Cylinder Head Pontiac Performer D-Port 72cc Chambers for Hydraulic Roller Cam Complete

When you're rebuilding the top end of your 1962-79 Pontiac V8, the Edelbrock Performer D-Port Cylinder Heads are a solid choice. These heads are built for 389, 400, 421, 428, and 455 cubic inch engines, specifically those with a 4.060" or larger bore. They come complete with guide plates, rocker studs, and a high-quality valvetrain, making them a direct bolt-on application right out of the box.

Edelbrock cast these heads with extra thick port walls and a compact port size, which is great if you plan on doing some CNC or hand porting to further optimize airflow for your specific build. They also feature improved oil return passages for better oil flow back to the pan, and the spark plug location has been moved closer to the exhaust valve to help boost performance. The D-Port exhaust configuration is designed to work with standard D-Port exhaust systems, and the heat crossover is machined to be 50-state emissions legal.

These heads are designed for use with hydraulic roller camshafts. They feature thicker deck surfaces than many other heads on the market, adding to their overall durability. If you're looking to get more out of your Pontiac V8, these complete cylinder heads offer a well-built foundation for improved performance.
