Is there no rake in your game? I'd estimate the pot to be ~$78. Shtack sizes would be nice as well.
To make the pf call profitable in raw equity, V's range should be as wide as the following:

Equity Win Tie
Hero 32.41% 30.75% 1.66% { KQo }
V 67.59% 65.94% 1.66% { 88+, ATs+, KQs, AQo+ }
I'd continue w/ KQo vs a thinking player who realizes a CO open is wide and prone to restealing. I might continue sometimes vs a nit who makes many overfolding errors post flop if we we're deep enough. Based on the V description, seems like we'll be stuck with a sticky, possibly aggro villain, so in this spot I'd let the K-high go.
Yes... the flop is a call. If we're planning on folding TP, then that's even more reason to not play pre.
