368 is the same block as a 317 so it should bolt right up

In a Ford, especially 54's, it was common practice to run a pipe down and back from the drivers side manifold (opening in the front) because either the neutral safety switch was in the way or the Z bar was in the way if using a later rear opening exhaust  manifold.  Sounds like what you are describing, but only on the passenger side.  Not familiar with the Lincoln exhaust system .

My 53 Ford Flathead had a wrap around pipe for duals that was available aftermarket. later model manifolds with rear outlets would make a much neater setup.
