My setup is 10 to 1 with 9-10lbs out of a vortech. So far I have blown one head gasket at the track. I am thinking it was BC I didn't run race fuel that one time but on the streets I have never had a problem with 93 pump gas. Normally I run race fuel at the track but that one time I got cheap and said screw it. I just bought a used snow stage 2 kit and some mls head gaskets for extra insurance. I can only speak from my own experience but I think it can be done no problem with the right tune. If you do decide to do it make sure you have enough fuel and know your a/f.
