Oh, yeah. Nope, not in the UK.
Indeed. I am in upstate NY. The car I had originally came from Utah.
That explains why the set of engines you listed didn't at all match what I saw here :-). So I still don't know for sure, then, that the engine my friend has now isn't interference, but I don't think it is. I don't recall ever seeing zetec stamped on it, and you say that would have been obvious if it was.
