Today's O8 hand- How valuable are a number of iffy draws

[lunchmeat]

Paradise 2/4

I open limp in EP with Ah, Ac, Qc, 6h. 5 others see the flop for 1 bet.

Flop: 8h, 7c, 3h

Checked around.

Turn: 9s (8h, 7c, 3h)

SB checks, BB bets, I fold (but I wasn't sure if I made the right play).

Here's what confused me about the hand. The flush draw had some value, but even if the heart came I'd split a small pot. My A6 low is marginal at best, but I may have the best low because only 2 more aces are in the deck, and an A2 would have probably bet and the 3h spoils A3xx. I folded because my hand wasn't too great, it could always get raised behind me, and the big blind bettor was a pretty good player.

Turns out the big blind outplayed me. He took low on river with 24xx... but do two or more iffy draws make hands like this worth a call?
