Inspect the Cylinder Head
First, inspect the valve guides and seats for wear or damage. Next, measure the valve-stem clearance. Also, check the rocker arms and camshaft surfaces before assembling the cylinder head.
This listing does not include valve guides or valve-stem seals. Therefore, inspect those parts separately and replace them when needed.
