Should I bother with a divided merge?

I'm thinking I'm going to run 1 and 5 , 3 and 7(driver side) then 2 and 4 , 6 and 8(pass side) into separate 2 inch pipes that merge into each side of the divided flanges. So two cylinders to each half of the flanges.
If anyone wants to chime in on the cylinder combinations, that'd be great. I've talked myself into and out of that particular order a couple of times...lol trying to keep the best exhaust pulse sequence in mind.
Thanks for the input guys!
