BB Chevy stocker Alum.head question

BobbyH · 08-30-2021, 02:56 PM

Does running the 401 alum. head option over the iron heads offset the weight penalty? I'm a novice trying to learn more about the rectangle port engine combinations everyone is running.I seem to notice the 396 guys running them,but hardly any 427's?What about the 454's? Does it work better on 396's than the others? I would think the newer head tecnology/casting would easily be worth more than 10 HP. Please educate me on the how's and why's Please forgive my ignorance all you engine builders......
