8-3/4 powr-lok

I have the 8-3/4 sure grip, dana powr-lok style. It has 2 thick & 1 thin clutch plate per side. The rebuild kit only comes with thick clutch plates, and says to re-use the thin plates. My thin plates have the ears broken off them.
So, what happens if I use all thick plates in this type of sure-grip? It will be tighter, I realize, but has anyone done this? Since I drag race the car, would it actually be better?
Thanks,
Jeff
