With the autochrome manifold, there is NO POSSIBLE WAY to get the nut in place, no matter how much you try
Also, that same nut that can only go on at that time...you have to tighten it first too. Once the manifold is tightened down, there isn't enough clearance between the valve cover and the manifold itself to get a wrench in there :-x
For these reasons I'll probably go back to a ported stock manifold with an external wastegate welded on when i upgrade turbos.
