Anyone know what the exhaust manifold thread pitch is for the studs?

I tried to put the old nuts on and the threads are hammered and look like they desperately need to be freshened.

 

Just take one to your auto parts store. They have usually have samples and will try yours until it fits one correctly even if you don't know if it's metric or english. I've went to an Ace Hardware for some of my hardware and they have actual commercial samples you can try yourself until you find what is just right. A well stocked one even has interior screws and body bolts if you're missing a couple.

 

I will eventually be taking the manifolds off to refresh the studs with the dye, I was just hoping someone knew so I could do it all at my friends garage and not make several trips.

Anyone have this info?
