If you decide to stay with the 400 I’ve got a set of #13 heads… ready to bolt on and run! They flowed 220cfm @ 28” on Rocky Rotella’s bench with just a mild cleanup and were visually inspected by Jim Hand after porting.
They were professionally assembled with all the good stuff: Ferrea valves, Comp Springs, hardened seats etc. Let me know if you’re interested… made right at 400hp/400lbft in my 400 with a Bullet 224/230 .485/.491 110LSA cam.
I have a 71 too btw so let me know what you need or if you have any questions as I've probably researched it for you already! LOL
Welcome to the site! This is a great community of incredible people!!
V/R,
Ty
