I usually start with 600 then 800 then 1000 then 1500.. If you want a mirror mirror finish go 2000 then 3000 then top off with a buff using a towel and some auto paint super fine swirl remover..

This if you do one you will not see a big difference unless you do the other.. The CPU IHS is typically more concave then a HS is as well..
And lastly unless you pull the h70 (hoses from block/pump assembly)apart its gonna be a task lapping it correctly... Which in turn means draining, flushing, refilling and adding a Res/t-line of some sort...Edited by G.E.Nauticus - 1/14/11 at 3:01pm
