Exhaust Leak - 318 Manifold

I'm sure there's a "right way" to do it, but I've seen flange gaskets and donuts used. There's a set of flange gaskets in my Fel-pro set which I plan on using, but when I pulled the exhaust off, there were some (completely dessicated) donut seals in there. I think my plan right now is to use some "ultra copper" on the flange gasket and around the manifold "ball", I've done that before and had good results as long as you alternate tightening the bolts so it goes in flat.
