Theoretical cam question

Thanks all! Would there be any benefit from installing 2.02 intakes over the 1.88's, while using the 268 cam? I have heard before that adding larger valves, loses bottom end some, on a mainly street motor. I am also toying with the idea of having the valves done in the heads too; however, if the benefit of that expense is marginal, i will skip that idea too.
So far this is what I have
69 Dart. 360 standard rebuilt short block. #587 port matched heads cut .050", 901 comp springs. Weiand Stealth intake port matched, 750 Holley, Hei Ign, 18*Initial,36* total. headers/duals... 727 w/2500 B&M converter, 8-1/4 SG 3.55 (have 3.92 not installed yet) Steel shim head gaskets (? thickness) I am planning on changing pistons to the Sealed Power H405cp. I don't want to go too high in compression cause i'm nervous of detonation or I would go to the h116. The car is only street driven. no track nearby. Does my plan sound good so far, and should I include larger intake valves?
