The GM 10239906 Cylinder Head is a cast iron Vortec head used widely on 5.7L (350 cubic inch) small block Chevrolet engines from the mid-to-late 1990s and early 2000s. Known for improved airflow and combustion efficiency, the 10239906 casting features upgraded intake port design derived from the LT1 platform, contributing to better throttle response and horsepower over earlier designs. This cylinder head was factory-installed on a wide range of GM vehicles, including Chevrolet and GMC trucks and vans, and also marine applications like MerCruiser. Vehicles commonly equipped include Chevrolet 1500, 2500, and 3500 pickups, Express vans, Suburban, Tahoe, and GMC Savana and Yukon models powered by the 5.7L gasoline engine, both in standard and CNG configurations.
