Thank you, I replaced the elbows with metal ones. Is there a web page that shows how to replace the manifolds in case I have to remove them?

This should help you out. Though the years are different, the engines are still the same.

Is there a preference for lower intake manifold gaskets? Found the Dorman 615-180 for 64.99

I would go with Fel Pro gaskets, they are now aluminum and seem to hold together way better than most.
