The head is the same but not the cam.....the euro cam is different from the US na motor and the turbo motor ....if you put a US na motor from the early 80s next to a euro NA motor from 82 or later they are VERY different besides the pump....thats why they are peppy not JUST because of the rear end....its the cam.....sadly though you cant use it on the turbo motor.
