I went with twin Turbonetics 72mm Mid Frame BB turbos. And the treadstone dual inlet, single outlet over the radiator intercooler. My goal is 1100rwhp with 398ci and T56.

Smaller turbo means you have to push the pressure ratio and shaft rpm higher to get the desired mass flow. Most shaft rpm means more heat. On an air to air equipped car thats not a good thing.
Your assometer couldnt tell the spool difference in a pair of 66's versus a pair of 72's no matter how much you may try and make me believe you can.
Oversize the compressor a touch...reduce required shaft rpm to make X hp and reduce the heat made getting there. Its the smart way of doing it.
And the Treadstone end tank design is garbage. Inlet is too close to the core. The tank is too skinny. Buy the proper sized bare garrett core and have someone fabricate better end tanks.

At what cost to reliability?

As for the intercooler, I only went the treadstone based on price vs reviews. The bigger turbos will lower the heat that the intercooler can't cool. Good enough for now.
I can't comment on how it all works yet though...

over sizing turbos is a waste.
you will lose spool time and gain no power for it.more lag and the same power? that sounds fun to drive.
for your combo id go with twin PTE billet 6262s no bigger.
i have PTE5858s on my car (a little smaller motor) and i think they still have more to give, 1k rwhp atlest

never the less over sizing the turbos hurts spool time with no benefit to anything, front or rear mounted.

And just imagine what it would do if the end tank design wasnt crap and the whole core was utilized not just about 60-70% of it.
