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

If you're working on a 1962-1969 Pontiac with a 455 cubic inch V8, these Edelbrock Performer RPM CNC cylinder heads are a solid choice for an improved top end. They share the same core specifications as Edelbrock's popular Performer RPM heads but add a key upgrade: a CNC machined combustion chamber. This precision machining results in a more consistent and accurate chamber shape, which directly contributes to better airflow through the head. The 87cc combustion chamber size is specifically tuned for engines aiming for around 9.5:1 compression, making them well-suited for street performance and capable of running on lower octane fuel without issue.

These heads are patterned after the port flange configuration of the 1969-1970 Ram-Air IV Pontiac cylinder head, giving you a familiar starting point if you're familiar with those performance components. Edelbrock also builds these heads with thicker deck surfaces than many other options on the market, which adds to their overall durability and reliability, especially when you're looking to get the most out of your engine. While these heads are designed for hydraulic flat tappet camshafts, it's always a good idea to consult the manufacturer's installation instructions for specific details on camshaft compatibility and any other necessary components for your build.

Keep in mind that these cylinder heads are not CARB approved and cannot be shipped to California. When planning your build, consider that these heads are sold individually, so you'll need to purchase two for a complete V8 engine setup. Ensure you have all the necessary supporting hardware and gaskets for installation, as these are typically sold separately.
