conical washers, the 1/4 inch (or so) thick ones,They are cupped. Raised center goes torward the nut.
They are used on the end studs only. they are to pull down on the manifold away from the hole where there is studs. they are to suppose to stop the manifold from cracking or stud Shear when expanding and contracting. After many heat cycles the manifold will shrink.
