Who makes a good quality OEM performance clutch kit?

When my truck came apart it had an 11" clutch. The disk actually looked fine, but the pressure plate had a few bent diaphragm fingers, so at least the pressure plate needs to be replaced.

I'd like to get a good stock clutch. Not anything fancy for racing, but I'd like to find something of equivalent quality that GM might have installed in a stock '70 Corvette or Z-28 Camaro with an LT-1.

I went to RockAuto to look for clutch kits and I saw them anywhere from $35 to $170. For brands like "Brute Power," "M-Pact," and "AMS Automotive." I have never heard of these brands. I usually prefer AC Delco to "keep my GM car all GM," but Rock didn't list them.

Does anyone have recommendations for 11" clutch/pressure plate kits?
