An approved solution as an alternative is having a qualified technician install new threads in the spark plug hole. Lock-n-stitch has approved spark plug thread inserts. This can be done possibly without cylinder head removal.

That's a link for some more info.
if the head is coming off, replace the head. ford has tons of issues with this problem. we replace the head with either a used one from one of the major engine manufactures or a new head from ford.
either option is not cheap.
