Waveski, when you had the intake off and on several times, what was the configuration for the exhaust crossover ports in the intake gaskets? Many intake gasket kits include several steel inserts so you can tailor the amount of exhaust heat crossing under the carburetor from one head to the other. If those ports are wide open with no restrictor inserts, it will add a huge amount of heat to the manifold and carburetor.
