Exhaust manifold bolts/hardware?

The end holes get studs, get them at the hardware store. They are in water jackets, seal them with hi-temp teflon sealer, they would like the conical washers. They are not that expensive. For a 318, if you want manifold to head gaskets, go back and get 273 gaskets. 340/360's are too large vertically. Grade 8 bolts for the rest. I have seen conical washers on all of the fasteners, or only 4 on the studs. Go ahead, make your day.
