You can't change the rocker ratio, so the articulation remains the same as it follows the cam, so the shims can only be there to make sure the rocker arms sits high enough so they don't hit the outer edge of the springs when in motion...

You have probably seen a million sets of wedge rockers on here that hit the outer edge of the springs...Makes a mess of the aluminum rockers.
