Trick flow 240 or 270 for 421 big block

Do you already have an intake manifold? Or what type of manifold do you plan to run?
My intake choice will be based on what heads i buy. I do have a polished tunnel ram for a b block...std port but right now im looking for what will work best on the combo and dont mind spending a few bucks on a nice mw port intake or different std port.
