Villain is very loose, aggressive preflop, passive postflop (54/18/0.6 in 37 hands). I read the villain as either having a weaker ace or is trying to buy a free card on the flop. Reasonable to raise the max or is a slower line better?

I like a slower line. Call here, punish him on the turn... Or if he checks the turn too, check the river and punish him there. Reasoning? You're likely ahead here. There is no reason to scare off a bluffer. If you check to him on the turn, yes he might take a free card, but I think it is more likely that he has a weaker ace and will fear that you are drawing. However, if you check the river (after he checks the turn) he'll try to bluff his busted flush or value-bet his ace. Yeah, I like slower play.
