Thanks for all the help.  I think I've found NOS bolts and washers.  I'm waiting on a phone call to verify measurements.  I'll have to refinance the house to pay for them. LOL

I think you can anneal copper using the opposite technique to steel.
Heat them up until they are glowing and then quench them.




This is what I remember from metallurgy class!

When you tighten a soft copper washer it work hardens. The more times you use it the harder it gets. Grainger says their copper washers are annealed which is a heat treating process to soften them. Did you ever bend some copper tubing? bend it once is easy. Try to bend it again-- not so easy.

Tony,what happened in the process to make the new washers useless and are the granger washers of the type that will work.
Dan, if the old washers didn't leak before the overhaul then they were fine, you'll take them off and they will be groved from the bolt digging into them, but they didn't leak before, if there is enough washer I'll run them over a file to even them out and reuse them.
