In one of the old Smokey Yunick books I have, he commented on how he didn't know how drag racing valve trains even held up given the extra lift and spring loads they used compared to the roundy-round engines he specialized in. I think at that time a .600"-ish SFT cam was probably typical for his stuff, so a more aggressive solid roller with .750" lift and 600#s open pressure would have seemed... "different", for sure.
