400 stroker suggestions

Have the exact same motor in my demon I would like to do something very similar with the shumaker tri-y headers..but I was thinking more of ole faithful "451"....my first big block I'm clueless..has been sitting 5 years perfect candidate to stroke!! You already seem to know a good bit more so I'm anxious to see your responses because a "470" could very well be the monster I'm wanting to create also..good luck with info !!
