commando's vs. eddie rpm's

Not trying to hijack the thread here but it seems like the people who know heads are all reading this thread anyway, so I have an Edelbrock head question. Since there is no provision for the exhaust crossover with these heads, will an aluminum six pack intake manifold ever get hot enough to open the automatic choke? Can you just back it off a bit & get it to work? Or would it be better to just set it so lean that it never really does anything?
