Oh yeah if the bridge pulls up when string tension is applied, that'd obviously also lift the action way high...see it's about flush with the body for best results. I like to leave a teeeeeny weeny gap there because I think it affects the sound some; if it's screwed down very tight to make it a hardtail, it loses some of the liveliness with it. A big part of why a strat sounds like a strat is the trem, even when not used and torqued down quite tight.
