I bet $70-80 and obviously call a push. I want to get some action from a hand like QQ/ Ax which may be more likely to fold to an overbet push but even feel he has fold equity if he pushes.

Given your odds of making full house the flush draw is going to be winning on turn 7/45 or 1 in 6.5 times. By betting $80 into $115 with implied odds for the rest of your 80 stack you deny correct odds for the flush to chase and don't need to fold even if a heart hits - especially given your redraw possibilities.
