Right, I think he was saying if you went the other way to bump the compression back up (by using smaller gasket, shaving the head, whatever), there's plenty of space to do so, and then you might need to go to a higher octane fuel to keep things happy. If the bike already required 91, there's less room to up compression for more power before things get more stressed.
