This isn't a good sign.
You're going to pull the threads out.
I would soak the plugs in some Penetrating oil a day ahead of time. Then warm the engine and try it.
GO a little pressure clockwise and a little pressure CC and see if you can't get a little movement and then work it back and forth from there.
Other wise you are going to get into a heli-coil situation. If it goes well.
