Great Story!
I really dont know anything about Olds engines but find a local burnishing company and have them polish up any aluminum parts you have. They basically tumble them in a polishing medium and they come out pretty good looking (not like polished aluminum rims but good) and its relatively cheap. I have no clue where you are actually located so I cant help you with where to go. I have a great place in Los Angeles I go to. Just make sure to take any brass fittings off as the acid will eat them up bad!
Every Olds I have seen has a really low profile intake manifold stock so you might look into that. Other then that just replace every hose, belt and wiring that may need addressed as preventative maintenance.
