I would only cut them at the base of each cola. I mean really it's all a matter of personal preference, but I wouldn't dig too deep into a bud as to cut it into shake. Use your better judgement. If they are dry enough for cure then they ought to look like they do if you were to buy them cured at a dispensary, except for maybe a few color changes. The basic shape of each nug should already be there though at this point.
