All I have ever seen is that Ford just stated that the two injectors would have "different operating characteristics" and that interchanging them could cause rough operation. I know that this had a lot of discussion in the early days. A number of people posted up that they interchanged them and didn't experience any issues. I don't recall anyone ever stating that they interchanged them and DID experience rough operation. A few Techs even said there shouldn't be an issue interchanging them.
The difference is a "diamond-like coating" on the plunger.

That's how I remember it too (C2 to C3 I believe). The coating helps prevent wear, but they are a little more efficient in operation. The software, however, will slow down the injectors to the worst one, which is why one poor injector can cause poorer performance then one might expect.

From the 2004 6.0L Updated Coffee Table Book:
Injector Clevis
• A change was made to the injector clevis
mid-way through the 2003 MY.
• The revised clevis in the injector improves
the lateral support of the plunger and
dramatically reduces injector scuffing
Of course there's no mention of part number changes if any.
