Quantifying the value of position in limit HE

[catlover]

I am curious if anyone has ever tried to quantify the value of position in limit HE.

For instance, here is a problem whose solution would interest me very much. Players A and B both put two small bets into the pot. They are both dealt a hand in the top 40% of possible hands. A flop is now dealt, and they play limit HE through to the river, with player B having position.

What is player B's advantage in this game, in small bets per hand?
