The villain was quite loose and passive (with small sample): 35/12/1.1/47/50 [VPIP/PFR/AF/WTS/Hands]
With over pair, on heavy board like this, what should I reaction to his shove? (Look back on PreFlop round, I think he could call my Raise with a PP, like 55, 66 or 99, but here we've got an overpair! 
)
You most likely are beat there without any specific reads. Although overall I don't like your bet sizing there. I'd myself most likely bet a bit bigger and then we would be pretty much committed.
