Problem after plug removal!
So a friend was helping me with the removal of my spark plugs on my 06 F150 5.4L. First one we do its a bitch to get off. After its out the threads on the plug were just terrible. Looked like they are cross threaded or something. I guess the person who changed them previously didnt get them in right and striped the threads. Then we thought we would try another one....same problem. Ended up just putting the old one back in and figured I better take it to a shop now. Is the head up now or does it just need to be re-threaded?

First thing is when changing plugs on an aluminum head always do it cold engine or you'll take the head threads out with the plug. Also the 5.4L has only 3 or 4 threads in the head ( another brilliant idea from Ford engineers) and they can work themselves loose by themselves which sometimes causes thread damage. This can be repair with a helicoil. If you can't do it yourself there are specialty shops like The Drill Doctor who can do it.

Helicoils do NOT work long term - Timesert is the only repair that you can do yourself that will last.
