2001 LS1 SS

My MTI S2 heads are on order, and I asked them not to mill them down any more than they have to (.010) so that I can add boost later. So this will take my CR to 10.2 or 10.3, but I'm wondering if I should have them add a half a point or so. Plan to S/C next year with 9 or 10 lbs, wondering what the highest CR can be with that? Just don't want to sell myself short on HP from CR but also don't want to limit myself when I go to 'Charge it......

Thanks
