ctsv with ls9 clutch and engagement issues

So I had the ls9 clutch installed a while ago and had some engagement issues where it was very difficult to get into gear when running. Reverse was by far the worst . I have put almost 1200 miles on the new setup. I have put in a new slave, master, tranny mount, new atf fluid (syncromesh), bled many times with a power bleeder. So I came to the conclusion it must need to be shimmed. Well I pulled out the tranny measured the distance from the transmission surface to the top of the fully compressed slave with the throwout bearing. The measurement was. 1.58in. I then measured from the bellhousing surface to the pressure plate fingers. The measurement was. 1.68 in. So normally they recommend .175-.225 of spacing. So I'm at a loss for the issue as it obviously doesn't need the slave to be shimmed. Help please!

Difficulty going into first or reverse is usually due to the clutch not disengaging all the way or dragging.
Here are a few common problems to look for:
-Hydraulic system not bled entirely
-Hydraulic system leak
-Improper bleed procedure
-Bent disks (this can happen if you let the trans hang during installation)
-Other physical damage to the disks or flywheel
My advise is to post your bleed procedure so we can take a look at it. After that keep bleeding. Let us know if each time you bleed you're getting bubbles, or not. After that the next thing to try is a new clutch assembly, assuming the one you bought is damaged or defective. It's rare, but it can happen that the clutch is defective. Or it could have been bent during installation.
Hope that helps. Keep us posted.

I have the transmission sitting on the floor now and there are no signs of wet marks/spots or any leaking of the hydraulic system (which is entirely new both slave and master).
I have not yet removed the clutch but this will be the next step in diagnosing the issue.

The hydraulic system was bled at least 5 times. I used a motive power bleeder. Hooked the bleeder up to the master cylinder pumped it up to the appropriate pressure (8-10 psi IIRC) and cracked the slave bleed line open for about 5 seconds. closed it, checked the motive bleeder pressure and made sure it was still feeding properly, then did that 3-4 more times. I followed this process about 5 times.
