The utility model discloses a cylinder head of engine, which comprises a cylinder head body (1) and a combustion chamber (9), wherein an air inlet (4), an exhaust port (5) and a spark plug hole (3) are arranged on the combustion chamber (9), and combustion chamber measuring benchmark bosses (10) are arranged on a central line of the spark plug hole (3) and the side edges of the spark plug hole. The cylinder head can guarantee to measure and control the height and the height difference dimension of the combustion chamber after each time mechanically manufacturing the bottom flat surface of the cylinder head, thereby guaranteeing the capacity and the capacity difference of four cylinders of the manufactured high-efficiency engine to satisfy the requirements of the design. During the operation of the engine, the petroleum products are more fully burnt, the compression ratio can be improved to the higher power, and the durability of a fuel system is protected in maximum, and the burden of later maintenance is gre
