3 valve head swap

I hear that the way Ford upped the power in their 5.4L from '03 to '04 was to swap from the 2 valve to the 3 valve head. If that's true, I wonder if a 3 valve head will swap directly in on an '03 motor?

The head will swap no problem.But the wiring is a issue all by itself.Not to mention the 3v does not use a throttle cable it is an electronic throttle.
