Also I'm thinking that when it was running lean and by the o2 sensor when it was gettin red hott that it melted the catalytic converter and maybe cause the head gasket to blow

I believe your on the right track. Earlier you stated the manifold was glowing red. Due to all those misfires it probably did melt the catalyst which is causing excessive back pressure. The noise your hearing is probably from exhaust not being able to get through the catalyst. This can cause the engine to run hot or possibly overheat, but maybe you should confirm that catalyst is restricted by performing a back pressure test with a gauge screwed into the front O2 sensor. I don't think the duratecs were known for blowing head gaskets, but you should fix the catalyst problem and then see what happens.
