These are all great questions and suggestions. I haven't had the manifold on my car yet to see whether I need heat or not, I just presumed from previous experience that I would probably need it. And I agree with it being too rare to monkey with in a permanent way- that's also a major concern. Now I don't know whether sidedraft versus downdraft carbs play any part in the heat equation either? I'm sure the first thing is to bolt it up and see how it runs- but first I need to rebuild the carbs...
