Only reason flop could be a fold is if he sometimes is bluffing with a better flush draw, but I doubt he ever is, besides OP was nice enough to tell us the results that villain has a set.
I figured all of our outs are pretty action-killing. Even if we hit our gutter, you don't think villain would ever suspect 54s & not pay us off? Although I guess most people don't fold sets ever, so I'm probably wrong.
