Kickup :- the shims go under the FORWARD MOST block (less shims = more kickup)
Whilts it is possible to adjust hinge pin height by adding a spacer under the rearmost FRONT block and removing an equal sized spacer from under the FORWARD MOST front block this is very rarely done

Antisquat :- this is adjusted with shims under BOTH blocks.
(Ideally you want to adjust the antisquat without affecting the hinge pin height so if you want to increase the anti-squat by the equivelent of the 2 pip spacer your best off making a change of an extra 1 pip under the FORWARD most rear block & adding a pip spacer under the REAR most rear block.)

A lot of people don't do this and just add or remove a spacer from either the front or rear block (normally rear as easiest to get to).

You can increase anti-squat by adding spacers under the FORWARD MOST block and/or removing spacers from under the REAR MOST block.

Say if you wanted to get 2.25deg anti-squat, you have 4 options (although best not to put a 4 pip spacer under the FORWARD MOST block as this can cause issues with the block touching the driveshaft).
If you achieved it via having the 3 pip block under the FORWARD mount and 2 pip under the REAR block you would have a higher hingepin height than if you achieved it by a 1 pip spacer under the FORWARD block and no spacers under the REAR block.
Generally (as a rule of thumb) a higher hinge pin will give less grip mid & late corner than a low hinge pin.

Hope that has helped (but expect it has probably confused instead)
