This is a rebuilt head and somebody installed fatter valve guides. Already purchased sets from Autozone and Rockauto. They are all 0.010" too small in diameter.
Here is a decent photo:

It's simply matter of fixing the shell part (no sealing function) to the valve guide. All the function (sealing) happens at the rubber, spring reinforced ring. Hell, I could drill and pin it. Maybe cut a groove into the guide with a dremel and stake the thin shell into the groove. The thin copper shell cup that fits over the guide does not have to seal, only hold on and not go on an up-and-down ride with the valve.

Any suitable glues? BTW the cap (shell part) seems to be about 0.010" copper.

Thanks again.
Try Loctite 638. It is good for gaps up to .01". It resists hot motor
oil well. Use brake cleaner to degrease the valve guides. Spray the
cleaner on a rag and wipe the guides clean. Same for cleaning the seal
cup. Don't get the seal itself wet with the cleaner. 638 is permanent,
so make sure you really want the seal cups glued on.

No knowledge of use but the spec page looks promising for what
you want to do:
