From various sites I've read online while doing research on fixes, it seems the early 5.4l 2-valve engines had 5 threads in the aluminum heads which lead to the blow-outs. They "fixed" that problem in 2002 with the 3-valve engine and 8 threads. The problem is they didn't redesign the head and instead went to a 2-piece spark plug design which was not fully threaded and that lead to the next round of problems for the Triton which was plugs seizing and breaking off in the heads...
I found this kit from CalVan tools which is similar to the TimeSert kit and only $230 so I may have him buy this one instead. Either way, it will be a long weekend if we can get the tool in time.
You got it basically right, but I think the 3 valve did not come out till around 2005, not 2002.
