hi, few years ago, the EPA banned asbestoes use in clutches. mcloed tried kevlar to replace it. I tried one of those. they didn't last very long. I was told, they ended up having disc made in mexcio with asbestoes. those seem to work better. you might try a mcloed B&B/long pressure plate. the pressure is lighter, and you can put C/W on fingers. I used those for years, they work very well!! 3200 # is way too much pressure in a clutch. I had 2400 # to start with.
 
I'm using a zoom kevlar clutch with a 68 lb steel flywheel on the street. it's welll behaved, engages easily and I like it.

I have a pro street 71 duster with a blown 340 and 5:13 Dana Rear.
