The practice is varied, but I believe pre-20th-century composers thought in clefs, not transpositions. Most were keyboard players with considerable clef skills.
What you're dealing with is a matter of philology. Depending on the level and philosophy of creating an edition, I suggest the edition be in the appropriate key for the pitchset of the horns with a note about the source. F parts are never a bad addition to a set of parts, though unnecessary for the score.
