What is the primary benefit of the 72cc combustion chamber?

The 72cc combustion chamber is designed to increase the compression ratio of your engine. This generally leads to improved power output and throttle response, especially in performance-oriented builds.

Are these cylinder heads a direct bolt-on for all compatible engines?

While designed to fit 1962-79 Pontiac 389-455 c.i.d. engines, specific installation details and potential modifications should always be confirmed with your mechanic or by consulting the manufacturer's installation instructions.

What is the significance of being patterned after the Ram Air IV head?

The Ram Air IV was a high-performance factory option for Pontiac engines. Patterning these heads after it means they incorporate design elements known for their ability to generate significant power and airflow, making them suitable for performance applications.

Product Details

Starting with the 72cc combustion chamber, these Edelbrock Performer RPM cylinder heads are built for Pontiac engines from 1962 through 1979, specifically those with 389 to 455 cubic inch displacements. They take inspiration from the well-regarded 1969-70 Ram Air IV Pontiac cylinder head, aiming to bring that level of performance to your street performance build, daily driver, street rod, or muscle car. If you're looking for noticeable gains in throttle response and power across a broad RPM range, from 1500 all the way up to 6500, these heads are designed to deliver.

These heads are a complete package, featuring the highest quality intake and exhaust valves along with robust valve springs, so you can be confident in their reliability. The design focuses on providing significant performance improvements for your Pontiac V8. They are patterned after a legendary head, meaning they bring a proven design philosophy to your engine build. This makes them a solid option for anyone looking to extract more performance from their classic Pontiac powerplant.

When considering an upgrade like this, remember that these heads are designed for higher compression engines. They are not CARB approved and cannot be shipped to California. Ensure compatibility with your specific vehicle and engine configuration before installation.
