The implied odds (in no/pot limit) are there, but they do increase proportionally along with the number of players in the hand. I should have stressed that the "real" value in these hands is that they are "made hands." If played correctly (against 1 or 2 players) they will be positive EV. I don't think that you need to raise everytime in every position with these hands, but you should be raising at least 65% of the time to get the most "value" from them. Playing them 100% of the time as "speculative hands" is not going to be +EV IMO. Check your PT stats to see how you are doing with each hand, try raising them and compare your results. Another benefit to raising PF is your post-flop decisions will be much easier.
P.S. Don't take my word for it, but definitely read "Harrington on Hold'em" Vol. 1 for a better explaination of the points that I'm trying to make.
