Agreed, I have run aluminum for almost 2 decades now. It's just the complaint/rant like post of why don't they make aluminum heads look stock. IMO, a silly compliant. Not that I don't think it would be cool, it is just they after market probably won't do it just because we think it's cool.'The W2's will perform, looks stock to most eyes. But you have to want a iron head to do a iron headed engine.
