it all depends on who you talk to really.. you can make iron heads work as good as aluminum, but you gotta port them alot to get them to flow like alum. heads do out of the box.. alum heads work better for blowers..
I'll stick with my AFR's.,.. I'll probably get another set for my 68 too... dump the ported 66 heads that are on it now..
