Ditto +1. I've done it (grab it like superman unbending a steel bar and pull) for slight spreading (4 or 5mm) just to allow an easier squeeze, but forks are dangerous things to compromise. Then next time you're in tuck going down a steep hill at 40mph+, you'll be very worried about front end integrity.
