they're not the same 2.5L motor nor are they the only versions. The forester has yet another version of the 2.5L with a turbo as does the Legacy GT. It's also fairly similar to the NA version which is used in many subarus.

Is the 04-05 STi 2.5 motor the same as the 06-07 2.5 motor then?

It ain't just the heads. Subaru has more versions of that 2.5L than you can shake a stick at.
