Supposedly those engines have individual coil-on-plug for each cylinder so the spark plug is underneath the individual coils. I would also be extremely careful while doing it cuz of the known issues with breaking plugs in the heads and that would be no fun at all.

It could be, it could not be. I've read about people who spray some penetrating oil on them couple days in advance and follow the actual Ford procedure and have no trouble. Then I also read about people who do the exact same thing and they break some. Just gotta be careful and take your time. If the plug isn't breaking lose easily, I would stop trying to force it. Once you start forcing things, **** is going to break.

The 5.4 has individual coil packs on each plug that are connected by a 4-5" boot. The 5.4 Tritan is notorious for stripping out the aluminum head when changing the plugs (assuming the motor doesnt shoot them out on its own). Take your time or get used to putting heli-coils in blind (down a 6" hole that you cant see).

If you got access to a oxy-acetylene torch, try heating the rotor up around the studs and center hub. Also, there may or may not be two small threaded holes in the center part of the rotor in between the studs. If the rotors have these and you can find bolts to thread in, then you can keep threading each of them in going back and forth between the two to force the rotor off evenly.
