Slant 6 Aluminum Performance Head

Are people wanting a aluminum head that basically a replacement but that can make 200-250 hp with out porting or is it that you want some race piece that can do 400+ hp ??

From what I understand s stock head needs porting to make 200 plus hp and a max ported head can do 300 hp so other than weight or going for over 300 hp which is probably fairly radical /6 I don’t see need for a aluminum /6 head. Be nice for the few but the stock head with work can accomplish what most peeps need.
