Edelbrock Cylinder Head Performer RPM CNC Pontiac 1962-1969 455 CI V8 87 cc Combustion Chamber

Edelbrock is well-known for performance parts, especially for American V8 engines. This Performer RPM CNC cylinder head is built for 1962-1979 Pontiac 389-455 cubic inch V8 engines, offering a significant upgrade over stock components. It's designed to improve your engine's breathing and overall performance, making it a solid choice for rebuilding or enhancing your classic Pontiac powerplant.

What sets these heads apart is the CNC machined combustion chamber. This advanced machining process ensures a precise and consistent chamber volume, which directly translates to improved airflow and more efficient combustion. The 87cc chamber size is particularly well-suited for builds aiming for around 9.5:1 compression, delivering strong street performance even on lower octane fuel. These heads also share the same port flange configuration as the legendary 1969-1970 Ram-Air IV Pontiac cylinder head, a nod to their performance heritage.

You'll also notice these heads have thicker deck surfaces compared to many other brands, which adds to their overall durability and reliability, especially in higher-performance applications. This is a complete cylinder head assembly, ready to be installed on a wide range of Pontiac, Buick, and Oldsmobile V8s from the mid-60s through the late-70s. If you're looking to get the most out of your Pontiac V8, these Edelbrock heads are a well-built option that offers a notable step up in performance and consistency.
