Edelbrock Single Perf SBC 64cc Head Comp

If you're looking to rebuild or upgrade the top end of your small-block Chevy engine, these Edelbrock Performer cylinder heads are a solid option. Designed for 302, 327, 350, and 400 cubic inch engines, these heads offer improved airflow over stock castings, which can make a notable difference in how your engine performs. They retain the stock intake port location, meaning you can use your existing intake manifold and headers, simplifying the installation process.

These particular heads come with 64cc combustion chambers. This size is often chosen to help retain the stock compression ratio on earlier small-block engines, particularly those from 1970 and prior, which is important for maintaining drivability and emissions compliance. The heads feature high-flow intake and exhaust ports, and the complete assembly includes larger-than-stock 1.46-inch valve springs that are ready to handle most high-lift camshafts you might install. Edelbrock also machines a heat crossover for 50-state emissions legal performance, making these a versatile choice for a wide range of builds.

When you're putting these on, remember that cylinder heads are a critical part of your engine's breathing. Ensuring a clean mating surface on both the head and the block is key for a good seal. These heads are built for a range of vehicles, including many Chevrolet and Buick models from the 1960s through the mid-1980s, so check the fitment details to confirm they're right for your specific application.
