You got it WRONG. Guides come only in one size from Nissan(P/N : 13218-53J00). I suggest you check your old one(if they are all the same size), and reuse them. After that, facing the engine, you calculate the difference in height between the left(with guide on this one) valve and the right valve, with the tool posted earlier. You write that number on a paper, and do this for every cylinder, intake and exhaust side. So you'll have 8 measurements. Then you order the shims that you need, and replace them at the right spot. So yes, THEY ALL HAVE THEIR OWN SPOT!!!
Do not place them anywhere, or you'll have a very loud valvetrain, that will wear out prematurely.
If you don't understand that, you should really bring that to an engine shop that knows what they're doin...
