Mechanics downloaded codes that referred to Ford TSB #05263. Due to misalignment of the cylinder heads the valve seats recede which causes a misfire and low compression on #6 cylinder (confirmed by mechanic). The recommended repair consists of replacing the cylinder heads at a cost of $2000 plus.
Ford website indicates that this is not a common problem (less than 30%) but happens to 2004 through 2006 3.0 liter V6 vulcan motor.
I was wondering if others have had this problem, what was their repair, and how successful was the outcome?
A failure rate of less than 30% is a common problem IMHO.
The only fix is to replace the head assemblies with the updated design heads along with the associated bolts/seals/gaskets.

A failure rate of 10% for the same problem is pretty high in my opinion.
Generalizing on your situation, before even considering spending that kind of money I would take into consideration the miles on the truck, oil consumption if any, and what shape the piston rings are in.
Thanks for the responses, now if Ford would only stand by their product and help with the cost of
repairs.
@dizzly is the misfire that bad?
Perhaps a very competent machine shop could repair your cylinder heads.
You may want to talk to a machine shop about your problem. Maybe they’re aware of it and will know if your heads can be repaired and/or if they’re not worth messing with.
