5.4 3v plug question

[TJH64]

I have a 2004 F150 Supercab FX4 with the 5.4 3v in it, bought new and now has 140,000 miles on it. Roughly 80% of these miles are highway use.

Anyway, this thing is overdue for the plugs to be changed. Ford put 100k mile plugs in these things(?) and now the truck has developed a slight mis. I have read and heard nothing but horror stories concerning the removal of these plugs, as the plugs have a tendency to break in the heads during removal. There is a special Rotunda tool specifically for this application, so Ford knows it is a problem. Any of you guys that work in shops familiar with this problem? Has anybody ever done a plug change on one of these engines?

Thanks

the tool is to fix the messed up threads, it doesnt really aid in the plug change, just in the repair of the damage caused...
