Tighter quench at a given CR will ALWAYS provide the best results....right up until the piston starts hitting the head.....LOL Once youve figured where that will happen thicken the head gasket by .003 and that should be just about right.... 
Seriously, most LS1 engines (with their tighter piston to wall clearance and minimal piston rock) can be run as tight as .030 (piston to head). Usually with a factory set-up (say .007 out of the hole) an .040 gasket works perfectly, That leaves your quench set at .033
Run the tightest quench you are comfortable with and mill the head to get your desired CR....

Thanks guys ... my Performance Shop owner got the go-ahead from me to order my AFR 205's and I'll go with their reccommendation. Their advice is in sync with what Tony just said. JRP previously gave me some good information, as well. I just hope now there's not still a 5-6 week backlog ... will be well worth the wait, though! Anyone know if AFR got more folks trained up on those milling machines?

The Yank is great ... hits hard as hell ... great converter ... getting a Trans-Go shift kit installed next week (hopefully) to allow my 16 y.o. son to drive it a little easier. Sticking with my 220/220 cam until I can get my motor forged late fall, then, I'll go with a TR 224/228 cam ... shouldn't be much of a difference, though, between these two cams.
