Would 2" primary headers hurt a D1SC procharged 347

Currently making 550-600 rwhp out of a procharged LS6. Plan to upgrade the shortblock soon to make 750rwhp, then swap to a f1r and make about 950. I am getting new headers now and do not want to have to upgrade again later. Would 2" primary headers hurt my performance too much now? I know I could do 1 7/8 but the 2" are only $40 more and seems like they would do better once I am making 950. The rest of the exhaust is 3" true duals, but I could add cut outs from the 3.5" collectors on the 2" if it would make a big difference.
Thoughts?

I have a set for sale for quite a bit less than they were new if you're looking for a set. There's pictures in the items for sale thread in my sig.

Your gonna need those once you upgrade to the bigger blower believe me. These prochargers like to breath. I gain 70rwhp when I open my cutout. I need some bigger headers but I dont have the $$ right now. Im using some 1 3/4 Pacesetters right now.
