no tim, this is strictly a 5.4 thing.

You can heilacoil new threads into the head and just put in a new plug, I forget the site that makes the special thread insert tool for mod motors, but check out the truck forums they will know.

Ford will tell you that you need to pull the motor out to replace the head, and to pull the motor out, they lift the body off the frame.

You can guess its very expensive, just buy the thread kit, unless there is damage to the head itself.

They lift the body off the frame of a superduty pickup?

yea they can lift the body i am not 100% sure on the f-250 i know the bed lifts off , but on the town cars the body is bolted on the frame and you can unbolt it .

Its pretty common on the 5.4's, seems the 99's were the worst about it. Check out ford truck world forums. or ftw.truckmoxie.com

You can help to avoid it by making sure you dont have a loose plug. Does seem like something Ford should stand behind though....
