SBC Performer Cylinder Head - Assm.

The SBC Performer Cylinder Head Assembly from Edelbrock represents a precision-engineered solution for small-block Chevrolet engine builders seeking reliable performance gains without exotic complexity. This bolt-on cylinder head assembly is engineered for street and strip applications where consistent power delivery, improved combustion efficiency, and proven durability matter. Whether you're refreshing a tired 350 or building a weekend cruiser, the Performer head delivers the breathing improvements necessary to unlock dormant horsepower while maintaining stock-compatible installation.

Edelbrock's Performer series is built on decades of small-block refinement, featuring optimized port geometry that enhances intake and exhaust flow without requiring custom manifold fabrication. The casting design incorporates superior cooling passages to manage heat under sustained load, while the valve seat angles and combustion chamber shape promote efficient fuel charge mixing and flame propagation. The assembly arrives fully assembled and ready for installation—eliminating the need for separate valve spring replacement or advanced machine work on standard small-block applications. The compact 10.25-inch width ensures fitment compatibility with traditional engine bay configurations and existing accessory mounts.

This head assembly is ideal for enthusiasts upgrading carburetor or early fuel-injection small-blocks, and serves as an accessible entry point into mild performance modifications. Installation pairs with stock or mildly modified intake and exhaust systems; however, maximum potential emerges when paired with compatible cam profiles and tuned intake manifolds. The 30.9-pound assembly integrates seamlessly with 283, 327, 350, and 400 small-block Chevrolet platforms, making it a versatile choice for engine swaps, restorations, and power-adder projects that demand reliable flow characteristics and proven longevity.
