How much would be left on the table?

My cam is a solid comp custom grind, 250/[email protected], and .584/.568 lift, 275/288 adv, and a 104 lsa (yeah, I typed it right lol.) I will only have 1.5 rockers, and those specs are for 1.6. I am going to have 2.08/1.65 valves put in (would that make a big difference in flow over the 2.02's?). I will port them myself, from what I have seen and read, you dont have to do anything extreme to get good numbers out of them (I hope lol). I do want to study up on the short side and find some pics of how it should be. The heads are the 995 long valve econos with 70cc chambers, I couldn't remember the exact compression so I just kind of estimated for the purpose of this post. Zero deck flattop JE with 2 valve reliefs, 4.100 with a 4" stroke. The guy I bought the shortblock from had them custom ordered (I still have the spec sheet) for 12.5:1 with 60cc heads. Forged crank, H-beams, girdle, bushed lifter bores, the machine work receipt is huge.
The intake is a toss up, either a Strip Dominator or an Indy single plane. 3.73 gears for now, 68 Dart 2dr post, 904 (I will get a custom converter). I will run 3" exhaust and probably turn it down right after the rear, for now.
I am really contemplating a larger cam. I will go solid because I can't afford a roller right now. Even thought of sending this one to Bullet for a regrind, but I want alot more lift and the duration at .050 to be in the 260s. I would also like to bleed of some cylinder pressure.

Does the combo sound ok? Anything you would change, or maybe a cam/specs in mind?

Thanks moper!
