Generation III cylinder head for V8 truck, van, SUV and perfomance applications often called an LS6 head. It has cathedral shaped intake ports and D shaped exhaust. The combustion chamber is slightly smaller and more efficient than the earlier heads used on LS1 engines. These heads helped the LS6 produce more torque than the LS1. The exhaust port is D shaped to improve flow.
