Edelbrock Cylinder Head Pontiac Performer D-Port 87cc Chambers for Hydraulic Roller Cam Complete

With this purchase, you're getting a complete set of Edelbrock Performer Pontiac D-Port cylinder heads, ready to bolt on. These heads are specifically designed for 1962-79 Pontiac V8 engines displacing 389, 400, 421, 428, and 455 cubic inches, provided your engine has a bore of 4.060 inches or larger. They come fully assembled with guide plates, rocker studs, and a high-quality valvetrain, making them a direct bolt-on application for your build.

Edelbrock has engineered these heads with a D-Port exhaust configuration, meaning they'll work with standard D-Port exhaust systems without issue. You'll find optimized oil return passages to ensure increased oil flow back to the crankcase, which is crucial for keeping your engine properly lubricated under load. The spark plug location has been moved closer to the exhaust valve, a change that contributes to improved performance. The casting features extra-thick port walls and a compact port size, which is great news if you plan on further CNC or hand porting to tailor them to your specific engine build. The heat crossover is also machined to meet 50-state emissions legal requirements.

These heads feature thicker deck surfaces compared to many other options on the market, adding to their overall robustness. If you're rebuilding the top end of your Pontiac V8 and looking for a well-built, complete cylinder head assembly that offers improved performance and emissions compliance, these Edelbrock Performer heads are a solid option.
