596 casting or 308 casting for mild 360 4bbl

Thank you, gentlemen, for your thoughts. I am thinking I will use the 596 heads as I already have them versus pulling the 308's out of the yard and having them checked.

At that point might as well swipe a set of magnum heads (any thoughts)?

My intended use for a daily driver with good useable power under the curve I am not going to to be racing it (I have my coronet for that) but I want a nice classy driver with all the creature comforts for those rare days I don't feel like being on 2 wheels.

This Magnum fits the bill except in the stock 360 2bbl form she is a slug, next improvement after the engine goes back together is going to be a set of gears that should really help get the big girl moving a little quicker.
