it would be to your advantage to have each of them as close to the same length as you can get them. not every cylinder gets equal air flow so youre not going to help yourself by furthering that impedance with short runners. it also doesnt help if you decide to go with some kind of forced induction. with a wet nitrous system like i have on my altima, there are already 2 cylinders that dont get as good a mixture as the others. are you building your own perhaps? if you are, id like in on it in some way.
