Do you mean it grinds when you try to put it in gear or it actually grinds just pushing the clutch pedal to the floor? Also, is it a grinding or a screeching sound?

You used the correct shim right? That can be a related issue with this if the clutch isn't engagin all the way then you will get those grinding noises.

If its anything like the ls1 then they go behind the slave. They allow proper spacing so that the slave wont over/under extend. In this case it would sound like the slave is over-extending because its not pushing the clutch disk tight enough. But yes it could also be a clutch fork but I don't have much experience with those. If you are overextending the slave you run a high risk of blowing it out and having to replace it. Be careful about that and take of this asap.

Hmm, everytime I hear about this problem, it's with a Spec clutch 
There are no shims for the LT1 T-56's as the shim is LS1 specific...
Unfortunately, the only fix seems to be grinding the fork
But before you go doing that, make sure the fork was installed properly to begin with as they can be a bit tricky...
Make sure the fork fully snapped in and that the bolts are tight...
If it still touches, break out your Dremel

little update:
went and made sure everything was correct and all was..........and still hitting the pressure plate. Bolt to the fork was tight. So I took it off and grinded the fork like everyone says. Installed it an all looked good. Good clearance and all. Then i go to push the clutch and it takes awhile to come back from the floor. I go to push it again and it hard as a rock. Then my buddy gets in there and decides to push it as hard as he can and we hear a pop. It was only the line that popped out under where you you fill the master cylinder up at, right below the brake booster. So I re-attach it and there is no pedal feel at all. I guess cause it needs bled now??
So we quit for the night.
Im guessing the fork somehow wasnt installed correctly somehow and being solid and not letting the hydraulics work correctly. That giving the hard as rock pedal feel??????????
I'll keep you updated
feel free to comment
thanks

Hmm, sounds like you may have blown out the slave cylinder....
If the fork wasn't properly installed when you pushed the pedal down, then the slave could over overextended (which would cause a mushy pedal)...
Once it extends as far as it can possibly go, you get a stiff pedal...
I'd check the fork again and make sure it's properly positioned on the slave...
If not, take it apart again and push the piston back into the bore by hand, then reassemble the fork and bleed the system...
If the slave doesn't actuate after that, then you might need a new one

Exactly my thoughts.
Were about to head back out there.
I'll let you guys know.

fork wasnt in all the way so I put it in right and started it up and pushed the clutch in and walla!
You can hear a slight slight grind when it's all the way depressed if you get under the car but im not worried about that. It should stop soon.
I know it's not the best way to fix this. It's pretty ridiculous fix but it works.
For those who might need to do this in the future.
I ended up grinding 1/8" where the pressure plate was hitting the 2 spots on the fork.
Also like the "how to" page, it said to grind a paper thin amount on the "T mount" and the same on the bolt that goes through it.

I may be going with the same clutch
