What is the advantage of the 64cc combustion chamber size?

The 64cc combustion chamber size is chosen to help you retain your engine's stock compression ratio. This is often desirable for street performance applications where you want improved power without the excessive compression that can lead to detonation issues on pump gas.

Are these cylinder heads compatible with any camshaft?

These Edelbrock Performer RPM cylinder heads are specifically designed for use with hydraulic roller camshafts. They come complete with appropriate valve springs to match this type of valvetrain.

Can these heads be used on a 1975 California emissions vehicle?

No, these cylinder heads are intended for pre-pollution controlled vehicles only and are not CARB approved. They cannot be legally shipped to California due to emissions regulations.

Product Details

These Edelbrock Performer RPM cylinder heads feature 64cc combustion chambers, a design choice that helps maintain a stock compression ratio for your Small-Block Chevy engine. They are specifically intended for 1955 through 1986 Small-Block Chevy applications, making them a solid choice for street performance builds, daily drivers, street rods, and muscle cars where you're looking for that noticeable seat-of-the-pants power increase.

You can expect these heads to deliver improved throttle response and a broad powerband, pulling strongly from around 1500 rpm all the way up to 6500 rpm. Edelbrock includes high-quality intake and exhaust valves, along with appropriate valve springs, to ensure reliable operation right out of the box. This particular head is designed for use with hydraulic roller camshafts and features a straight spark plug angle, which can be important for clearance in certain engine bays.

It's important to note that these cylinder heads are intended for pre-pollution controlled vehicles only and are not CARB approved, meaning they cannot be legally shipped to California. If you're building a classic performance engine and need a well-built head that offers a significant upgrade over stock, these Edelbrock Performer RPM heads are a popular option.
