My son and I are building 2 460's.....one radical for the strip/some street....one tamer one for the street that I already have cast heads for. I come from the old school (60's early 70's) when aluminum heads were taboo for the street due to different expansion rates of the different metals. Are things different now? My son is insistant on this and I need some input as they are a hellava chunk of change to purchase.
Thanks a bunch, Mark
