I have no dog in this fight, being that the fastest I’ve gone with my stocker is .60 under(so far), but I have a set of $250 lifters in my engine, a cast camshaft that is plenty big, and not all that much spring pressure, and everything seems to be ok in my valve train. The only thing adding roller cams to all cars in stock is give an advantage to racers that can afford another probably at least $2,000 in a roller cam, lifters, and valve springs to match. And don’t be tempted to buy cheap roller lifers. They can cause similar catastrophic events as a schubeck that experienced valve float one too many times.
