only reason i would consider aluminum is they are lighter, cool better and cost about same a having a set of cast heads redone because most all i have found are a few hundred for the heads then the machine shops want $500-$700 to go through them, do guides and valve job, so why waste money on fixing a cast when you can spend the money on aluminum if i ever decide to go with a bigger cam, better pistons, maybe even a stroker kit at some point ill already have decent starting heads, i dont really want to want to run magnum heads.. down here in texas mopar small block heads m **** mopars in my area are scarce
