600CFM carb

Re: 406 SBC
Your carb would be too small, except that those heads will not get you anywhere near 400 horses, Why even consider them? You need to find some better heads, or at least have those cut for 1.94" intake valves, plus have the machine shop drill them for the steam holes that are needed for use on a 400 block.
