My local Ford dealer says they honor any warranry except Fidelis (the one Rusty Wallace is pitching during every commercial break).
Just call your nearest dealer and speak to the service manager. Call your warranty too, they can confirm your coverage on that item.
I searched BBB and WarrantyDirect gets their highest ratings of A+ so that would be a good place to start. The Ford ESP seems to cover 7 years from date of first purchase which won't help me that much.
I had a dealer quote me $3500 because they have to replace the heads due to oil passages tht getter blocked and they have a tendency to crack when re-torquing them down, but they told me not to do the job due to it could be bad again in 10 miles or 100,000 miles as it is no guaruntee
