At a certain point in a balls out application I think it is easier to pick up 2, 3, or 5 hp compared to the difficulty of dropping even a couple pounds. For something the size of an intake manifold especially, I would want aluminum.

Another thing I have to add is that aluminum is much better than SS at transfering heat, thats what all this discussion is about. But consider that it works both ways. Heat may be transferring out of your intake charge. When I touch my IC pipes after a run, they are often hotter than the ambient engine bay air. I assume the engine bay air is probably cooler yet when moving at 100+mph. Of course, the better your IC is the less you have to take this into consideration.
