You lap the heatsink...it's the easy one.
Some people do lap the suface of the GPU or CPU, but it's more difficult.
Find a flat surface like a good kitchen counter or some thing similar and place a pane of glass on it (maybe 8 in x10 in). A sheet of newspaper under the glass would help avoid scratches to the counter.
Get 2 grits of sand paper, maybe a 200 and 600 grit in full size sheets.
Place the sandpaper rough side up on the glass and sand away to your desired finish.

It works too.When you start lapping ,you can see the parts of the HS surface that are higher than the rest of it.

Just be careful and apply even pressure over the whole HS or one side will be shorter than th other side when you go to clip it on the cpu. Uneven pressure=cracked core.
