Head and cam selection help for 440

You’re going to spend X number of dollars.
What are you hoping to get from it?
That fundamental question has nothing to do with flow numbers.

If you don’t know what your own expectations are, then I don’t know what anyone could say to help you.

I already told you the “potential” of the TF heads is over 200hp more than the stock heads(they flow 100cfm more).
That doesn’t mean that when you bolt them on to a 425hp 440, and change NOTHING ELSE, that you’re now going to be making 625hp.

This one got a roller cam and 1.6 rockers, and the good intake manifold:
