I've heard that they fit... but then again ive also heard someone say putting an sbc into a stang is a good idea. Hopefully someone can clarify better for you.
Edit: Found this for you
Heads-
All 2.0/2.3/2.5 heads will physically bolt in place of each other, they all have similar
exhaust port shape and placement. All cams are interchangeable as long as they
are used with the proper followers. Later model ('95 and newer) roller cam
followers cannot be easily swapped onto an older head as the valve stem size was
reduced in the newer heads and matching slot in the follower was reduced.
Early 2.0 and 2.3 heads have the same small round intake ports spaced evenly apart, they
differ from each other in their valve sizes though
