Head and cam selection help for 440

Mine is a .030 over 440 with the same pistons he used and right at 9.5:1 currently with the 88 cc heads. I have a 1050 cfm carb. So im starting with basically the same bottom end and compression ratio, my difference is i have bone stock heads. So from here, i can either pay to have my iron heads ported, OR, use that money for a set of nice aluminum heads but wouldnt be able to afford to port the aluminums. Thats why im asking if any of these aluminum heads ootb outflow the stock unported iron heads enough to warrant buying them instead of porting the irons..I will have around $2500 to put into heads and a better cam. Its been a while since ive messed with this stuff but IF i remember right, everyone used to say not to bother with porting the iron heads because you can buy aluminums that outflow the irons ootb and are lighter. now i know a set of ootb aluminums wont outflow a set of fully ported irons, im asking will the ootb aluminums outflow the stock un-ported irons by enough to warrant buying them rather than spending the money to port the irons..and then that link i put about the CNC ported speedmasters which are $400 more each than the same non CNC heads, so does this mean these heads DO indeed come somewhat ported over the non-CNC heads? Also, i dont HAVE to change the cam, but i have read over and over about how much better their is out there than the MP cams, and if that is true, i would like to get something that will create more power, especially with better flowing heads.
