Soviet pilots trained a number of NK pilots, but mostly they were instructors who stayed out of combat. It's very possible (and I think that there are a few documented cases), that from time to time they came into contact with US fighters.

The TV show I saw interviewed Soviet pilots that flew missions. They were not allowed ot fly over American held territory so that they could not be captured if they were shot down.
