I never even complete the blinds with unsuited garbage like this, but if you think these guys are bad enough to pay you off if you hit a monster, I guess it's OK.

Post-flop is fine, and I'd go ahead and call on the turn. It's cheap, you're closing the action, and you're getting more than good enough implied odds to draw to the full house. As you can see these guys didn't give a shit that the board paired on the river so you would have won a huge pot if you'd made your full house.
