I have a 3v 5.4

You're screwed now! Game over man!

paul i think you may be pleasantly surprised mine was missing at the top of 4th and 5th they didnt look bad but i went away with new plugs

Good to know. I hope you're right! It would be nice to solve the problem.

Have you driven it yet?? Whats the status?

It's broke.

The problem is excessive carbon build up around the electrod's porcelain tube. If you do routine induction and fuel injector flushes that should break up and remove the carbon so there won't be a problem removing the plugs. On vehicle with exccessive mileage we usually flush the induction and fuel systems two times and then remove the plugs on a warm engine. Motorcraft carb cleaner is the best to use to remove the carbon after you break the seat on the plugs and let set with the carb cleaner. Usually only 1 or 2 plugs will be a problem, but that is when the remover comes in handy.
