Default The Infamous Sticky Clutch Problem

Okay, so I have a sticky clutch and tried looking at JonB's write up on ways to get by this issue:
https://ls1tech.com/forums/manual-transmission/742741-sticking-clutch-pedal-write-up.html

This is what I have done...
A)Brand new clutch master cylinder (GM Dealership)
B)Drill mod has been done to the master cylinder
C)Brand new slave cylinder (GM Dealership)
D)Wrapped the the clutch line with heat shield
E)Using Dot 5 Clutch Fluid
F)Blead the car conventionally and with the pressure bleeder

REV 1st, shift to 2nd(smooth shift), REV, shift to 3rd(I get locked out of 3rd gear, and the pedal is completely stuck to the ground).

Therefore, the only thing left I think would be causing this is the Clutch & Pressure Plate.

I just had a buddy of mine speak to a highly recognized preformance shop that specilizes in Camaros/Corvettes. He was told that it's just the way those cars work and it doesn't sounds like a clutch issue. I was thinking about replacing the clutch with a LS7, however they said I would be wasting my time & money because I would still have the sticky clutch problem.

OKAY, if you can't get on the car, what the hell is the point of having it?!

Someone PLEASE help me out. I really have no direction to turn, and I don't want to drop my tranny again and replace any more **** until I know that replacing/added/adjusting/etc... will actually get the job done and make that clutch not stick.

Quick Mods I have on my car... Longtube Headers, Exhaust, Ported TB, B&M shifter. Mostly bolt on's. However, nothing that really has to do with the hydrolics of the clutch.

Wow. I was going to suggest doing the drill mod and if that doesn't work, to replace the entire clutch master, but you've already done that. The next thing would be to change to a different fluid, but you've already done that. Are you sure you're bleeding it right? Sometimes it takes a LONG time.

If you are on a stock clutch, that IS your problem. The fingers on the stock clutch flatten out at high rpm and it won't let you shift. I didn't do a drill mod, bleed the clutch or anything when I swapped to a RAM, the problem just went away.

Get an LS7 kit and a 1/8" Spacer behind your slave, and wave byebye to your clutch problems.

SDPC has the LS7 Clutch/PP/Flywheel kit for $399 last I checked. The spacer is easily homemade, but I think there are sponsors that sell it.

Oh... a +1 on the drill mod being bs. I've never done the drill mod, and I've been clutch problem free for about 1 1/2 years. That spacer made all the difference in the world.

The drill mod may be BS, I can't say for sure. When my car was a 6 speed, I changed the clutch, flywheel, pressure plate, slave, and clutch master all at the same time. I use a SPEC stage 3, GM slave, and Mcelod clutch master.
