Here is the information on guide replacement that I found for you.
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.0035 inch, .0155 inch and.0305 inch oversizes.
