Hurst break in period?

But, again, it is a personal decision. May not be for everyone, so that is a choice up to you.
One other than you may want to do is change out the fluids. This should be done as part of regular maintenance, and can assist in taking some of the notchi-ness out of it.

Are you still using the leather shifter that came with the car? You might want to try a taller shifter which will give you better leverage.

If you installed the shifter right out of the box:
1. Change to 1 set of the lightest springs. Adjust set screws to spec.
With this change, the centering mechanism will be much better than OE. You won't miss a shift w/ the Hurst, and your shift times will be quicker.

It seems the shifter stops are indeed needed per the following post on another forum:
PROBLEM
If you use a shifter with no shifter stops, then you are relying on the guide plate inside the transmission to limit your throw into each gear. Normally, this would not be a problem. You can take each slider and put it in every gear as far as possible (until it rests against the gear), and the keys stay in, and everything is hunky dory. HOWEVER, if you take the slider and try to put it into 4th gear as far as possible, you will notice that the keys will try and pop out. When they pop out, they pop out twords 3rd gear, and actually get locked on the 3rd gear blocking ring, and cause it to semi "engage" 3rd at the same time. Once this happens, and you have two gears engaged at the same time, the weakest part goes, being the syncro keys in this case. They shred in half. When this happens, it makes it almost impossible to get it out of 4th gear, as the half sheared keys left act like a wall and catch on the slider.
NOW, the reason this doesn't happen to everyone, and usually takes a while to happen is simple. The ball on the guide for the gears actually stops on the tranny case for 2nd, 4th, and 6th. It is the case that stops you from going "too far" into 4th. What happens is simple, after many hard shifts into 4th, you begin to dent the aluminum case, which allows it to go into 4th "too far". Like I said before, you can't go "too far" into ANY gear and cause a problem EXCEPT for 4th. The reason 4th is this way is because of the design of the gear and the distance between the input shaft and output shaft.
SOLUTION
The solution is VERY simple, use a shifter with stops, and adjust them correctly!! I know, sounds simple, but often the hardest problems require the most simple solutions! After 4 rebuilds of getting 50 miles each rebuild before getting stuck in 4th, I discovered this, and adjusted my shifter stops correctly. Guess what?!? 10K miles now!!
I have rebuilt over 50 T56's here locally. I have run into two other T56's so far with this exact same problem. Each time using a shifter with stops has solved it.

I do know GM used to use transmissions with Aluminum shift forks (which are prone to bending), in 2003 they went to steel forks.
I felt mine was too stiff when it went in. It has loosened up progressively since then, and is now a nice light, precise action. I was even running a taller shift **** for a week or so to try and gain back some mechanical advantage, since the shift effort was pretty high.
I backed the adjustment screws out one turn when I was doing my post-install double-check a week later, and now, with a few hundred miles worth of shifts, and that one change, it's literally perfect for me.

When I first got the shifter, it was so stiff, that my fiance drove it around all day in town one day in 3rd gear, because she wasnt pushing hard enough to get it into first!
Last time she drove it, a few days ago at my last autocross, she thought I had put the stock one back in, because the effort is sooo much lower now. It'll loosen up a bunch, and if it's still not enough, don't forget the lighter springs.
I'll never take this one out - the improved shift feel is wonderful. I love this car!

*edit* I also had the shift **** higher to give me more leverage earlier on. Now it's soft enough that I have the **** threaded all the way in.
