Wow, classic nightmare story. Sorry to hear it. Clueless gorillas should not be allowed to work on aluminum heads! There are so, so many stories out there. People used to working on old idiot proof iron headed engines should retire or get some education before playing with aluminum.
Turns out some CG installed a Heli-Coil in mine after the PO overtorqued plugs and stripped them. Heli-Coils are awesome for many things, but NOT sparkplugs. Yes, it blew out.
You can get rebuilt cylinder heads from Clearwater Cylinder Heads with solid inserts properly installed in all plug holes for under $1K for the pair. Check it out. I did and have been pleased so far. Only 10K miles, but lots of towing with no issues.

Spark plug blowouts is a common problem on the Triton engines. (4.6L/5.4L/6.8L) In any case, this repair can be performed on the vehicle without removing the cylinder head. Heli-coil products should NEVER be used on a Triton engine. Heli-coil "save-a-thread" or the Heli-coil "coil spring type insert" do not work on these engines. If a Heli-coil product has been installed in your engine and fails there still are more options available in doing the repair! I've done at least 600 Triton spark plug repairs and as of yet have never had to remove the cylinder head. Dealerships and garages like to remove and replace the heads because it generates labour and part sales.
The 3 Valve Triton also has spark plug related issues, but in this version it doesn’t leave you stranded on the road. Spark plug issues come to surface when you try to remove them. At this time you may break one or all of the plugs in your efforts to remove them. Once again do not let anyone remove the cylinder head to do this repair. This repair should be straight forward for an experienced tech.
What I’m trying to stress to Ford owners is simply that the cylinder head should NEVER come off to do any spark plug related issues!
You might find this posted somewhere else, if so, could someone merge them for me?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

Why doesnt Ford admit this is a defect
My 2000 F250 has 155,000klms or about 100,000 miles. It had the plugs changed at 90,000 klms they were as new. Ive owned the truck since new and have used synthetic from the 600mile break in. I was a great fan of the truck until a week ago when it blew a plug and the threads out of the head. Pathetic design where by the plug only screws in about three threads. Fords answer was save your repair bill in case they ever have a recall. I recently bought an Coachman Epic Motorhome. I was hesitant because it had a GMC engine instead of the Triton V10 I had grown to love over the years. Smooth and powerful. Well as it turns out I am glad that I only have one lemon and not two. I am no longer an unqualified Ford fan.

Ford "fixed" the problem halfway through 2002 year by putting more threads in the holes. They made a blunder in '05 when they started using the long plugs in the aluminum heads where by the smooth shank on the plug below the threads build up carbon and break off when removing them. There are a few TSB's to deal with these newer '05 + plugs.
