Valve Guide: Service and Repair

    Valve guides are an integral part of the cylinder head and are not removable. If valve stem clearance becomes excessive, the valve guide should be
reamed to the next oversize and the appropriate oversize valves installed. Valves are available in .003 and .005 inch oversizes.
