Hey everybody just a quick newbie question I don't do a whole lot of engine work but I'm trying to revive my 2.8l I had some head work done and I'm ready to reinstall my lower intake manifold but unfortunately during the project my bolts and nuts and washers got a little jumbled so my question is which way do the beveled washers sit on the studs convex up or convex down. It's a silly little question and I'm a little embarrassed to ask over the Forum but unfortunately I can't come up with the proper Search terms to find a real answer Googling so if anyone could please help me out it would be greatly appreciated😅
