Default help selecting twins for a 5.3

I need help selecting twins. i have searched but have not come up with all the answers i need. I am doing a 5.3 with a cam, head studs, and rod bolts. everything else will be stock as of now. i would like room to grow with the turbos. eventually I'll get better heads and what not.

so the turbos im looking at are below. car will be street/strip. looking for 750hp range. I am wanting twins because i just had twin boys. so why not that be the reason to go twins along with other benefits of twin turbos. but i am still open to going single vs racing 7875 billet. please help me decide. TIA
