I think I might be sorting out my problem noise and plan on ordering header gaskets tomorrow. Anyone using high temp RTV on the surfaces as well?

We typically don't use RTV on exhaust manifold gaskets. I would run the GM gaskets if you already aren't and see if that helps. Look the flange of the header over as well and see if it is bent as well. You might find your problem there.

I got the Fel-Pro replacements... going to try it on that side to see if it fixes the issue and works better.
