About this part

Product Details

Edelbrock has been a well-known name in performance parts for a long time, and their Performer line is all about giving your engine a solid boost. These Performer D-Port cylinder heads are built for Pontiac V8 engines from 1962 through 1979, specifically for those with 389, 400, 421, 428, and 455 cubic inch displacements, and a bore of 4.060 inches or larger. They use a D-Port exhaust configuration, which means they're ready to bolt up to standard D-Port exhaust systems without any special adapters.

What makes these heads stand out is the attention to detail for improved performance and reliability. They feature optimized oil return passages to ensure better oil flow back into the crankcase, which is crucial for keeping things cool and lubricated. The spark plug location has been moved closer to the exhaust valve, a change that helps improve combustion efficiency and overall performance. The port walls are cast extra thick, and the ports themselves are sized to be compact, making them a great starting point for custom CNC or hand porting if you want to fine-tune them further.

These are complete cylinder heads, meaning they come fully assembled and ready for direct bolt-on installation. You get guide plates, rocker studs, and a high-quality valvetrain included, so you won't need to source those separately. The heat crossover is also machined to meet 50-state emissions legal standards, which is a notable feature for many builds. They are proudly machined and assembled in the USA, reflecting a commitment to quality manufacturing.
