Edelbrock Performer RPM Buick Complete

If you're looking to get more out of your classic Buick big-block, these Edelbrock Performer RPM cylinder heads are a solid choice. They're designed specifically for 400, 430, and 455 cubic inch Buick engines, offering a significant performance boost for street rods, muscle cars, and daily drivers. These heads are built to improve throttle response and power delivery across a wide RPM range, from 1500 all the way up to 6500 rpm, making them versatile for various driving conditions.

What sets these heads apart is their compatibility with small-block Chevy style adjustable 1.6:1 ratio rocker arms, thanks to the included adjustable stud and guide plate setup. This feature allows for more precise valve train tuning. With 68cc combustion chambers, they're engineered to achieve a 9.2:1 compression ratio when used with stock pistons, which is ideal for achieving noticeable gains in street performance without going overboard. Edelbrock has included high-quality intake and exhaust valves, along with matching valve springs, to ensure reliable operation and longevity.

It's important to note that these cylinder heads are intended for use on pre-pollution controlled vehicles only and are not CARB approved, meaning they cannot be shipped to California. They fit a wide range of Buick models from the late 1960s through the mid-1970s, including popular choices like the Buick Electra, Riviera, and LeSabre, as well as performance models like the GS 400 and GS 455. If you're rebuilding the top end of your Buick and want a noticeable improvement in power and responsiveness, these Performer RPM heads are a well-built option.
