C5 Masters do not have a functional restriction in the master assembly like the F bodies do.
But, They have a dampener built into the slave cylinder. All you need to do it pull the roll pin that attaches the short line to the slave and look within

There are three restrictions in the Vette's hydraulic clutch, two are easy to get to, one is hard. The first is at the exit from the master (easy), the second is in the 90 degree hard line bend in between the master and slave (hard), and the third is in the entrance to the slave (easy). These restrictions are in the 02 Z06 master and slave units, which I upgraded to when I had the clutch replaced. I presume they are in other year assemblies also.
I went the lazy route to fix them, I paid a hydraulics shop $50 to drill them out and re-assemble the lines.

The diameter of the hardline is not a designed in function dampener.
Yes, its smaller than the braided line, but not and issue. We (Exedy and I) measured pedal effort vs velocity (their equipment) and found the the only issue to be the on in the slave fitting.

restrictor... dampener... same thing. It's a reduction in the diameter inline, which slows the movement (volume) of fluid, especially upon release, and there are three of them on the Vette. Supposedly, they are there to dampen the "hit" when the clutch is released, to keep warranty repairs down on half shafts, etc. But, because they soften the hit, they also soften the initial grab of the clutch, and could cause it to slip or could contribute to the lazy pedal problem. Did removing the restrictors help? It's too much trouble to do just this alone, so I did the full meal deal, replacing the master, slave, with Z06 pieces, drilled out the restrictions, put in a Spec Stage II clutch and a Fidanza aluminum flywheel at the same time. No more lazy pedal, pedal feel is like stock, but it clamps like a **** and doesn't slip. Was it worth it? Yes, to me. If I want to slip the clutch, I'll let it out slower, if I want it to grab, it will.
