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......

I think this is the head you should be looking for. This was taken from the Edelbrock website. The Edelbrock #60547 Performer RPM Bare NHRA Stock/Super Stock Rectangle Port cylinder heads are designed for Big-Block Chevy applications. Cylinder Head, NHRA Legal, Aluminum, Bare, 118cc Chamber, 315cc Intake Runner, Chevy, Big Block. These cylinder heads deliver great throttle response and power from 1500 to 6500 rpm.

Good Luck trying to find a set.
