304 runs like crap when hot
My CJ7 project (almost roadworthy now) runs pretty well until it heats up. It sputters at low RPMs and even dies sometimes. When hot, it idles high when in park or Neutral, but almost dies when idling in gear (auto trans). Have checked the timing (5 degrees BTDC in neutral with vacuum line to distributor detached and capped). Do I have an ignition problem or carburetor (Edelbrock, no idea what model) problem?
I would start first making sure that every possible source of a vacuum leak is eliminated. Base gasket, hoses, tees, manifold fittings and intake gasket... all of it. See what you can find out and we'll go from there
Is there a way to eliminate all vacuum except advance on Carb? This thing did not run when I bought it, and I'm not sure it ever ran right with all currently installed/un-installed parts. At least one vacuum line has a screw in it to cap it off, the valve covers are aftermarket, I believe an air pump was once part of the factory equipment (part of power steering bracket is hacked off where I believe ot once resided), aftermarket carb, etc. What do I do here?

1974 CJ-6 being restored
All ports are capped on the manifolds. It's a 1976 CJ7. I know the passenger side exhaust manifold has been replaced. I think my best bet would be to remove/bypass all un-necessary vacuum/pollution control stuff, as I am finding out a lot has been hacked under the hood.
