broken exhaust studs
Well I finally got done porting and polishing my manifolds. Then I realized that when I took them off my donor car I broke the studs off where the two manifolds connect together. Well I was trying to unthread them and it'* impossible. I got me a couple of titanium drill bits and broke them trying to drill them out. What'* the best way to remedy this issue? I was thinking about a tap and die set but if I can't remove the old studs what good will that do me.

I don't know how much room you have left, but sometimes when you can't get them out the normal way, threading them in and out the other side works better.

Yes, i'm talking about the crossover pipe bolts. I don't have access to a torch. What about just cutting off the weld and getting some new brass exhaust bolts so I don't have to deal with it again. I have about 3/8 of an inch of threads to work with.

Ok I got the bolts out. I have 2 final questions. Is it necessary to use exhaust manifold gaskets and what are there benefits to painting the manifolds as compared to just reinstalling them with no paint? Hopefully I will get them installed tomorrow.

Paint will burn off and be gone in a week.
Use exhaust manifold gaskets and new donuts on the crossover and DP. Don't install anything without these 4 gaskets.

There is some grey epoxy based paint the resto folks use on iron manifolds to keep them looking like cast iron. It'* supposed to be pretty tough and bakes to a harder finish, but has no advantages other than looks.

This is the only DIY coating I've ever heard of or tried that works:
