BBC 320cc Alum Cyl Head Assembled

The FLOTEK BBC 320cc Alum Cyl Head Assembled is a fully machined, race-ready cylinder head designed specifically for big-block Chevrolet (BBC) engines. This product is ideal for serious engine builders, restoration specialists, and performance enthusiasts who demand OEM-quality construction without the factory lead time. Whether you're rebuilding a high-output street engine, vintage race car, or marine application, this assembled head arrives complete and ready for installation.

Built from premium cast aluminum, the 320cc chamber provides superior heat dissipation compared to traditional iron heads while maintaining structural integrity under sustained high-RPM operation. The design is optimized for mid-range to upper-RPM power bands, supporting aggressive camshaft profiles and elevated boost levels in forced-induction applications. Pre-assembled construction means all valve seats, guides, and port surfaces are precision-finished at FLOTEK's facility, ensuring consistent gasket sealing surfaces.

This head is compatible with all big-block Chevrolet engine families, including the 396, 427, and 454 cubic inch variants. The aluminum construction reduces overall engine weight, a critical advantage for street performance, drag racing, and vintage restoration builds where weight reduction directly impacts acceleration and handling. With its ready-to-install design, this cylinder head is perfect for those looking to enhance their engine's performance without the hassle of additional machine work.
