Strong flush draw

$2-$4 pacific, no reads yet but table seems fairly loose.
Hero is UTG +1 with Kc-2c
Preflop: UTG folds, hero calls (wrong I know but about to leave for work and I'm feeling lucky [img]/images/graemlins/grin.gif[/img]), MP, MP+1 and button call, SB folds, BB raises, all call (10.5 SB's)

Flop: Ac,Kd, 3c. BB bets, hero...

I see raising here as a good option cos I might get a better King or weak Ace to fold and hope that BB has got queens or Jacks or something.

However if I just call and go for overcalls to build a big pot, then I've got equity on my side don't I?
