Rebuilding the Ford Triton V10
Good article with details regarding production changes through the years. It is always nice to read sections like this also:

The V10 has offered great service and reliability with a life expectancy of 300,000 miles plus. These engines are reasonable to rebuild with a variety of aftermarket parts available for them.

REBUILDING The FORD TRITON V10

The three major ailments of the V10 are blown spark plugs, broken exhaust manifold studs and failed ignition coils.
Remanufactured V10s eliminate the spark plug problem by drilling out the aluminum spark plug threads and installing a threaded steel insert.

Failed ignition coils are common. In our 2003 LD, a failed coil was not noticed, nor was the CEL (Check engine light) illuminated. Driving for two hundred miles with no spark lead to the destruction of #2's cylinder's rings and bore, resulting in having a Ford-cerified remanufactured engine installed.

The third issue is rusted and broken exhaust manifold studs.
The threaded steel studs slowly rust away and will eventually shear off, cause by the pressure of exhaust manifolds heating and expanding. When the stud break, exhaust leaks will become noticeable and can result in cold, outside air entering and hitting the super hot exhaust valves, resulting in valve damage.
I have found V10 manifolds with up to five studs broken. The cure is to remove the manifold to either drill out the broken studs or to weld nuts onto the broken end for extraction. Either job is difficult due to the very tight space constraints.
Waiting to long to replace broken exhaust studs can also result in warped exhaust manifolds, requiring an expensive replacement.

When our V10 died at 106,000 miles, it had been performing flawlessly, without excessive oil usage, and had no noticeable changes in performance. Oil pressure had not changed over its life.
If the plug had stayed in place, it should have had a much longer life.

The new, Ford-certified engine now has 6,000 miles and runs exactly the same as the old engine. After break-in, it now sounds the same as all other 2-Valve V10s.
I expect the remanufactured engine to have a long life, especially since the blown plug issue has been addressed by switching the spark plug threads from aluminum to steel. Having new exhaust manifold studs and spark plug coils is another plus.

Larry any estimate on the cost of the new engine?

I think I had almost 5 studs on each manifold broken.  Welded a nut to remove them,  3 day job just removing studs 1 day installing the new Banks header.  OBDII monitor has saved me many times now with missfires,  catching them sooner than later.  2 blown out plugs repaired with one twice.  Over 220k miles
