Edelbrock Performer D-Port Bare 87cc

These Edelbrock Performer D-Port cylinder heads start with a compact port size and extra-thick port walls, making them a solid foundation for serious porting work, whether you're using a CNC machine or doing it by hand. They're built for 1962-79 Pontiac V8 engines with 389, 400, 421, 428, or 455 cubic inch displacements, provided your engine has a 4.060" or larger bore. The D-Port exhaust configuration is designed to match up with standard D-Port exhaust manifolds or headers, which is a common setup for these Pontiac V8s.

Inside, you'll find optimized oil return passages to help keep your engine properly lubricated, and the spark plug location has been moved closer to the exhaust valve. This change helps improve combustion efficiency and overall performance. The heads are cast with a 4.155" bore size and feature 87cc combustion chambers, a popular size for street performance builds that balances compression with good flow characteristics. They are also machined with a heat crossover for emissions compliance in 50-state legal applications.

These cylinder heads are fully machined and assembled in the USA. They come complete with guide plates, rocker studs, and a high-quality valvetrain, making them a direct bolt-on application ready to go. This setup is ideal for anyone rebuilding or upgrading their Pontiac V8 top end and looking for a well-built head that can be further customized for their specific needs.
