Hey guys, I just installed the headers on my 327, for some reason I can't get it to start now when its cold, it runs super rich, so rich that if i even start to choke it a little it just dies, floods super easy. I almost had it going this morning but the cranking got my negative battery terminal so hot that it melted. My wife had to drop me off at work. Would the headers cause this? I didn't have this problem before, not even a little. Should I just lean the mixture out? Thanks. (also, the headers are open right now, the exhaust isn't done yet and it starts ok when it's warmer in the afternoon)
