Instead of sealer I used JB weld on the threads/hole and tightened the plug flush with the surface.
I used the 1/16 plug because all the work was performed thru the 7/16 head bolt hole with little clearance to spare.
Thanks to all that offered advice.This was a unique problem and the fix saved another flathead.
