hughes rockers

Has anyone here assembled these rockers? I've been following the picture that comes with the set that says la style heads I have rhs heads but they are shaft mount so I guess this is the picture I should be following. The picture has line pointing to where the shims should be places but it says 15 and 30 shims as required. Does this mean I need to put one of each where the lines are pointing? And none where there isn't a line. Theres a diagram of it on the hughes adjustable 1.5 rocker page but I don't know how to put it on here.
