They make taps for that, or you could possibly get some old or new spark plugs since theya re cheap and cut slits into the threads to make it like a tap. Make sure you put some grease on it so it can catch most of the shavings.

Taking it apart is easy. If you can work a socket/wrench you can do it Santana.

ive seen that get it and put a slice on it so it acts like a tap and someitmes works and fixes the threads.. good suggestion, or go to oreilly they even sell the tap for spark plug holes like 10 bucks
don't get a tap, get a thread chaser. Looks like a tap, but doesn't cut any threads, just cleans them up. Also use some anti-seize on the new plugs and this won't happen again.

Yes, do this. This is the first thing to try. I would drop the header so you have plenty of room and try the thread chaser. If it doesn't work then heli-coil them, it's easy to do and stronger than stock. No need to pull the head off, thats overkill.
I read a thread awhile back talking about the blowing plug problem that the for motors had. I had to fix an f250 that I had. You can buy the tap at any auto parts store and tap it out but use the slolid heli's. After you get done you can rig up your vac with a straw and some tape and use it to clean out any shavings left from tapping the hole. It worked for me 7 times. I don't drive the truck anymore but I see it all the time and it's runnin just fine.
