I'm one of the few guys that still thinks there is a place, albeit limited, for iron heads. If you are looking for max power without other personal choice restrictions, iron seems silly.

But, if you are in the 500 hp or less bucket you simply don't need aluminum after market either. I am not an anti-Chinese guy, but if I can reach my goal with iron, and pay a local guy (my first choice) or a domestic guy $1600 to do work, that will be a serious consideration for me. In this power range, it is the weight savings that puts me on the fence.
