Cylinder head sits on the top of the cylinder block sealed in place with the head gasket and forming the combustion chamber. Obviously it is subjected to extremes of temperature, which it has to resist. It houses the exhaust and intake valves, the fuel injector and necessary linkages, and passages. Some heads also contain integral ducts and passages for the engine's coolant for transfer of excess heat away from the head.
Not surprisingly, good quality cylinder head has to be robust with good sealing capacity, as well as high precision to mate with other parts. This kind of cylinder heads are what PUFENG supplies.
