Hero fold or hero call with AA facing 4B jam on wet flop?

2/5, $1k max, 9 handed.

V1 - SB (covers) - 30'ish Asian guy. Changed seats a few orbits after hero joined the game, then disappeared for 1.5 hours to go play Baccarat (don't get me started). Was pretty active before he changed seats, but hasn't played many hands since he got back from Baccarat, about an hour before this hand. Don't think if I ever saw him 3B pre. Usually had a hand at showdown, but wasn't showing down a lot of hands.

H - UTG, ~$1400 - early 50's white guy. TAG. Had been crushing the table early on. Was up over $2100, but now up-stuck after being card dead for the last couple hours and getting coolered a couple times. Hero has proven very capable of making big bluffs pre and post, showing down a couple whoppers.

V2 - UTG+2, ~$900 - late 50's/early 60's white guy. Loose pre, sticky post, calling hero's c-bets and turn barrels with all his draws. Had been insta-calling ~80% of hero's pre-flop raises, inviting others into the pot, very annoyingly. Will bet with thick value, and semi-bluff flop or turn when hero checks to him, but doesn't seem to be going for thin value or bluffing rivers.

V3 - HJ, $~1200 - late 50's Indian guy, same guy who in a previous session flat called hero's UTG+1 3B with KK, and flopped top set, cracking hero's AA. LOVES to call hero's pre-flop raises wide, especially when someone has already called. Recent experience with this V shows he'll get sticky on flops and turns, and chasing his draws. He's basically a nut-peddler, who has never shown a bluff whenever he showed any aggression.

OTTH...

Hero opens AdAh to $20. all V's call. Everyone else folds. $80 going to the flop.

Flop is Kd7s4s. V1 x, H x, V2 $40, V3 call, V1 x/r $160, H 3B $400, fold, fold, SB jams all in.

Pot is $1940, with $980 remaining behind, so hero is being laid about 2:1 on a call.

Hero?

Hero's losing to 13 combos of 77, 44, K7s, K4s, and 74s, obviously, but hero's unblocking all of V's AXss, KXss, AKo and KX with one spade, 56, any XXss.

Is this just always a fold? Is anyone here finding a call?

Is anyone just folding as soon as V1 x/r's, or just flat calling with V2 and V3 still in the hand? Is 3B'ing over V1's x/r mandatory, knowing how sticky V2 and V3 are?
