Overplaying small overpair? live 5-3-2

[paco]

Over previous hour villian seems like pretty solid player. Has usually had goods when made a big move, but has been caught bluffing on one occasion.

Both of us have about 1200 in front of us

PF
Villian opens to 20 UTG+1
Hero in MP with TT raises to 60, villian calls

F: 924 2 [img]/images/graemlins/heart.gif[/img]'s
Villian bets 50, hero raises to 120, villian calls

T: 7 non heart
Villian checks, hero bets 200, villian calls after some thought

R: 9 [img]/images/graemlins/heart.gif[/img] (putting 3 hearts out)
Villian quickly bets 160, hero calls

Did ok? Too much? Can/can't call that river?--felt suspicious.
