Good that you got the head torqued back down. That hopefully will help with the head gasket seepage.
The two bolts holding the intake manifold to the exhaust manifold won't make any difference on how it runs. I leave those loose until I get the four nuts on the manifolds snugged up. If the four manifold nuts were a bit loose for a while it is possible that you had exhaust gasses getting by the gasket and eroded it causing a leak that can't be fixed by tightening it back down. Spray some starting fluid all the way around the manifold gaskets and carburetor mounting gasket while running the engine to see if the engine speed changes.
When you rebuilt the carburetor did you happen to forget to install the venturi?
