On the same note , ignoring the "Darkness" of such a question : would a single carb be better ? what are the ups and downs of this setup ,besides no balancing problems ?

But if I could get all 4 cylinders to suck from the same manifold the pattern would be V V V V V ... for which the simplest repeating unit is just V, which takes 1/4th as long. Something that takes 1/4th as long has a frequency that is 4 times higher and would be represented by shock pulses in the intake manifold/carb that are 4 times closer together. This is just another way of saying that the wavelength is 1/4th as long.
