I think the hole is 18MM now.

Someone has either drilled and tapped the hole for an old style Ford
18mm plug, or they have drilled and tapped the hole for a heli-coil
insert and the insert has somehow come out.

The best option is to remove the head and have it repaired or
replaced, using the correct spark plug.
