Edelbrock Cylinder Head SBC Performer RPM Straight Spark Plugs 70cc

If you're looking to get more out of your Small-Block Chevy, especially for street performance or muscle car builds from 1955 to 1986, these Edelbrock Performer RPM cylinder heads are a solid choice. They're designed to give you that noticeable boost in throttle response and power across a wide usable RPM range, from about 1500 all the way up to 6500 rpm. This makes them a great option for daily drivers that you want to feel a bit more lively, or for weekend cruisers and street rods where seat-of-the-pants performance is key.

What sets these heads apart is their well-built construction, featuring thicker deck surfaces than many other options on the market, which adds to their overall durability. They come complete with high-quality intake and exhaust valves, along with valve springs, so you're getting a ready-to-install package. Keep in mind these are intended for pre-pollution controlled vehicles, so they're not CARB approved and cannot be shipped to California. They are designed for hydraulic roller cams and feature straight spark plug orientation, which can be important for clearance in certain engine bays.

When you're building an engine, especially one where you want improved performance without sacrificing too much drivability, cylinder heads like these are a critical component. They work together with your camshaft and intake manifold to determine how efficiently your engine breathes. These Edelbrock heads are a popular choice for a reason, offering a good balance of performance and reliability for a wide range of Small-Block Chevy applications.
