intake/exhaust mounting, what am I missing?

@Dne007, on that end exhaust manifold stud, you have the incorrect washer. What you should have is a brass washer with a bevel in it that the castled part of that nut goes into. The washer you have is one of the cupped washers and it's installed backwards anyway and also in the wrong spot. The correct place for it is in the center top intake stud and flipped around from how it is now.
