Head and cam selection help for 440

Before I got the ported bv 906's I ran a completely stock 440-6pk motor 9.5>9.7:1, with that Team G and an 850DP f/wells, 4.88's 14x32's 4800 stall and that big .650 sft cam and went a best of 11.23@118+@33000lbs = 459fwhp....with the good heads that went to 10.7@125, 525+ just for reference.

E-streets prob only flow [email protected]" less lash/deflection around 520-ish" so 250cfm?, PRH would have more info on that perhaps...can't find flow no's for them, so I'd say nowhere near [email protected]:1.
I can tell you what it took to make 595hp with my mates 440, 12.7:1, MCH ported 320cfm Eddy rpm heads, .590 sft purple, victor intake, 2" hdrs 1050 Dominator, 4.56/13x31's/5000stall, 10.1's@131+@3150lbs.
