No. You don't do that. The unknown cards are the unknown cards, whether they are in the stub, the muck, or someone's hand.
As for whether the fold is good if you'd seen his hand, remember that you don't have to be over 50% to be +EV if the pot is offering enough.
Let's imagine that his raise was the last money thAt would go in the pot. If you called, 56.3% if the time you'd lose the price of your call, or $115 (-$64.75) and 43.7% of the time you'd win what's already in the pot, or $235 (+$102.70). That means that even though you're behind, you overall EV is +$37.91.
Of course, in this exact instance, thread is money behind that almost always goes in. So let's imagine that you shove and he calls. Now your EV is -0.563*320 (-180.16) and +0.437*440 (192.28). So even in this case, your EV is positive by about $12.
Of course, all that assume that you know his exact hand. Against his range here (SF draws, sets, Pair+NFD, 78s) you are crushed with only 21% equity and it's a super clear fold.
