What are the parts of cylinder head?

The cylinder head consists of several key parts, including the combustion chamber, valves (intake and exhaust), valve guides, valve seats, and spark plugs (in gasoline engines). It also contains passages for coolant and oil, along with mounting points for the intake and exhaust manifolds. Additionally, rocker arms and camshaft components may be incorporated, depending on the engine design. Together, these components facilitate the engine's combustion process and airflow management.
