Nitrous plumbing A1A...??..

I just ran into a possible first plumbing problem.. each kit came with two lines one is about 11 and 1/2 in in one is about 8 and 1/4 in.. at first I was thinking I could hook one of each 2 each solenoid but now I'm thinking 1 car would get fuel sooner and one card would get nitrous sooner? Or is it such a little difference that it shouldn't make a difference? We're probably talking milliseconds here??..
I'll shoot a picture or two.. I'm trying to orient these lines so they'll make it from the front of one carburetor to the back of the other carburetor for 1 T fitting and the opposite for the other? if I do one of each it seems to work out kind of evenly where are the solenoids may go..
