The Speedmaster PCE281.1083 is a bare aluminum cylinder head engineered for Chevy GM LS7 applications, featuring 245cc intake runners and a 60cc combustion chamber. The aluminum construction keeps weight down while promoting efficient heat dissipation, making it a strong foundation for performance street and race engine builds.
Sold as a bare head, this unit allows builders to source and spec their own valvetrain components for a fully custom assembly. Designed to fit LS7-based engines, it delivers the port volume and chamber sizing needed to support serious airflow and power potential right out of the box.
