sealing and covering the cylinder block is the main function of CHC. In some type the cylinder head cover is integrated with air cleaner and air intake manifold.
The cylinder head holds a lot of components and functions. For this reason, it is very important that it is properly set up. You need the appropriate configuration, tools and parts to achieve this.
The sub-assembly of a cylinder head refers to the collection of components that make up the cylinder head before it is fully integrated into an engine. This typically includes parts like the valves, valve springs, camshafts, and rocker arms, which are assembled together to facilitate the intake and exhaust functions of the engine. The sub-assembly is crucial for ensuring that the cylinder head operates efficiently, contributing to the overall performance and functionality of the engine. Once fully assembled, the cylinder head is then mounted onto the engine block.

the parts of the cylinder are the base and axis
Cracks can be welded and then the head can be resurfaced.
1988-1991 yz250 motors are completely interchangeable. Some parts like the cylinder head use the same casting from 1988-1996. Note: although interchangeable the cylinder ports and cylinder head combustion chamber shape differ form year to year. The optimum setup for a 1990 yz250 is a 1991 cylinder with a 1992 head.
