A head assembly, also known as the cylinder head assembly, is a crucial part of an engine that sits on top of the engine block. It contains essential components like the valves, camshaft, and spark plugs, which regulate airflow, fuel intake, and exhaust gases. The cylinder head seals the top of the engine's cylinders, ensuring compression and efficient engine performance. A well-maintained head assembly helps improve engine power, efficiency, and overall reliability.
