A cylinder head matching body, comprising a machine body (1), a cylinder liner (2), a cylinder head (3) and a seal ring (4); the cylinder liner (2) is disposed in the cylinder bore (61) of the machine body (1); the cylinder head (3) is fixedly connected to the machine body (1) via a cylinder head bolt; the seal ring (4) is disposed in the cylinder sleeve (2) and is airtightly matched with the inner sideline of a mated surface of the cylinder liner (2) and the cylinder head (3). With a simple structure, the cylinder head matching body significantly eliminates the bending moment on the cylinder head caused by the pretightening force of the cylinder head bolt, thus dramatically increasing the gas pressure inside the cylinder that the cylinder head can bear.
