Checque inner fender skirt to see if some previous mechanic has cut a long access hole in it and then covered it with a piece of sheet metal and screws. THis method was often used in service during the period

I'm not sure what the thaermal dynamics are on this engine but when setting them cold it mite be a good idea to set them .003 looser than hot spec. Then run the engine for a test. Better too loose than too tite. Most likely, as the engine gets hot the length of the valve increases (diminishing lash) but very little to no increase in block height.
