you can user any 05-early 07 head for the mustang 4.6L. you cannot use a late model year 07 as they changed the spark plug design.
You should also be able to use a 04 F150 3v Heritage edition head.
Awesome thank you!
Here is a real Noob question, What side is the passanger side is it from looking head on the car passanger = left or passanger = right?
Found a head woohoo ..
