you DO save some weight with aluminum, but you have other issues to deal with... the oxidation of aluminum can be a pain.. things liek to seize to aluminum very easily, plus they are very sensative to heat... and can warp easily as well... I know you can avoid all of these conditions with antiseize and not overheating your engine... but aisde from teh weight, the aluminum doesnt make the heads better.. other then the fact maybe the casting is of a different shape.. but flow is flow right? if you can outflow the edlebrock or TFS heads and do it for less, why NOT save the 200 bucks? I dont mind spending the money if I'm going to get something for it.. otherwise I can put myself on a diet and save 200 bucks.
