Why cant we use regular chevy clutchs?

Disc thicknesses are different. LS1 is thicker to take advantages of self adjusting clutch.
To answer you question, be careful using older GM discs making sure the inside diameter of the facing is greater than 7.6". Otherwise, it will overhang the pressure plate. I am not aware of an older GM 26 spline disc that has this large of a inside diameter.
The self adjusting mechanism will compensate for a thinner than LS1 disc.
You also need to check the cushion of the disc. That is how much it expands from a compressed state when you push the clutch pedal in. The LS1 pressure plate only lifts about .055", so you want your cushion to be less than about .035" so the disc will release properly.
