I bet 425 and go from there, for reasons already articulated by the "punish the draws" crowd.

Edit: to elaborate.... a small bet welcomes draws in, and if button calls with a draw or a T, then that prices in the other two behind us with as little as bottom pair. If it goes to the turn multi-way in a fairly big pot, then it will be very difficult to assess what cards are scare cards, and it will be uncomfortable to put our stack in (only reasonable turn bet considering the pot size) unless a K or non-heart Q hits the turn.
