But now it is time to hunt down the exhaust leaks and put the thing back correctly. Have you guys ever made any custom copper gaskets for this before? If so, how did it work out and how what did you use? Any ideas are welcome.

Buzz,
I didn't read the whole thread so if this has been suggested sorry for the repeat. I built my own headers and side pipes for my EM. I had a machine shop cut out flanges with a water jet cutter. At the same time I also had them cut out copper gaskets. I think I used .060 copper sheet. After everything was welded up I took my headers to another machine shop with the old style belt sander for surfacing heads. Had them run the flanges on the headers and the side pipes on the belt and that got them good and flat. Bolted them together with the copper gaskets with no silicone or anything. They don't leak at all.
If you have the old gasket you can take it to a shop with a water jet cutter or cnc plasma and they do you up some. Just a suggestion. Keep in mind the first set will be a little costly because of the CAD work to lay it out. After that its the cost of the material and cut. I have my own CAD program so I do my own CAD work and that saves me money. If you know someone who has a CAD program you can save some money. Its a simple layout so it shouldn't be much.
Looking at your pics your flange is likely not flat. You likely have a low spot where its blowing. You can use a large long bastard file on the flanges if you don't want to pull the headers.
