Ford E450 V-10. Problems with #10 cylinder

I have a 2007 Ford V10 E450 engine. Several mechanics including my son state that V10 engines spit out spark plugs, usually #10 that will lead to costly repair. Does anyone know what year Ford changed the heads to alleviate the problem. I have 40,000 miles on a Tioga, and am considering selling it. I love the RV. Ford has not been helpful. Thanks.

I have read, in these forums, many different dates when the problem was fixed. There have been many theories on what caused that to happen. Some say the head did not have enough threads, others say that the backyard mechanic did not torque them properly. This website Consumer Affairs seems to identify the Triton engines versus only the V10. One thing to keep in mind is there are 1,000's of V10's that do not have problems. :)

I have not heard anywhere that Ford admits they might have had a problem.
