thats a good idea, when i built my stroker, i ported and polished my stock HO head w/ casting number 7120 (a true HO head) put it on the flow bench, and it flowed more than the aluminum head on all ports according to Hesco's numbers on their Alum jeep head flow....either way, if i had the cash...id get the aluminum w/ the 2.02/1.60 valves, and then port the
out of it to get the best you can get.....jsut ran out of money for now
