Cylinder Heads

The cylinder head covers the top of the engine block and houses the combustion chamber, intake, and exhaust valves. It plays a critical role in the engine’s operation by allowing air and fuel to enter and exhaust gases to exit. Performance cylinder heads are often designed for improved airflow, which can significantly boost horsepower and torque.
