Edelbrock Cylinder Head BBC Performer RPM 348/409Ci for Hydraulic Roller Cam Complete

Starting with thicker deck surfaces than many other brands, the Edelbrock #60815 Performer RPM cylinder head is built for serious street performance on 1958-1965 Chevrolet "W" Series 348 and 409 cubic inch big-block engines. These heads are a great choice if you're looking for improved throttle response and noticeable power gains from around 1500 all the way up to 6500 RPM, making them ideal for street rods, muscle cars, and daily drivers that need a bit more punch.

This complete cylinder head assembly comes ready with the highest quality intake and exhaust valves, along with robust valve springs, specifically chosen to work with hydraulic roller camshafts. The design focuses on delivering that seat-of-the-pants performance feel that makes driving more engaging. Because these are designed for pre-pollution controlled vehicles, they offer a straightforward path to enhanced power without the complexities of modern emissions equipment.

When considering an upgrade like this, remember that these heads are intended for use on vehicles manufactured before emissions regulations became stringent. They are not CARB approved and cannot be shipped to California. Ensure your build is compatible with these specifications for optimal results.
