I used to get heel rub with Look Pedals and Shimano 600 cranks, but now that I run speedplay pedals I have adjusted the Q-factor to eliminate this rubbing.
I'm about to purchase a new bike and would like to know if I would be more likely to experience heel rub with 2005 Record or Dura-ace?
What are the q-factors for Record, Dura-ace and 600?
Adjusted the q-factor... do you mean you mounted the cleat inward on your shoe? You can do that with pretty much any set-up. Q-factor is the distance between your pedals -- heal-crank rubbing can occur w/larger or smaller q's.
Within one shoe-cleat mounting position, there's not much to tweak: you can use fixed-postion/zero-float pedals, or pedals w/adjustable float (i.e. Speedplay Zero's where you can adjust the inward float).

I have speedplay X/2 pedals. As I ride with my toes pointing outwards, I mounted the cleats inward so that my heels and the boney part of my ankle don't rub against the crank.
Since I have very narrow hips, I would like to have my feet as close to each other as possible without them rubbing against the crank.
