Dwight, we both know full well that the rockers Clark Holroyd sells are plain old stock rockers originally designed for truck engines, during a period where Chevrolet didn't have much interest in racing, and certainly not big block engines in drag racing, at least outside of Pro Stock. Clark Holroyd just has studs and adjusters made anyway, he just happened to see the rockers on a replacement engine, and thought "hey, I could use bigger studs with those". GM didn't design a "race piece" and then sit back and wait for Clark Holroyd or someone else to "discover" them.

No, a lot of the 396, 427, and 454 engines did not come with 7/16" pushrods and guideplates.

I agree, the open valve spring rule is what has caused this. We cannot "unring the bell", they'll never go back. The duration rule didn't cause this, because the shorter duration you're allowed the more you try to accelerate the lifter within the duration allowed. If you had the open valvespring rule without the open duration rule, it'd be even worse than it is.

The roller rocker rule is just another step towards a slippery slope, and it will make the playing field even less level than it is now. And where do we stop?

I have a friend that makes roller rockers, if the rule comes in, I can always have him make me a few sets that use 9/16" studs and be right back to where we are, because we aren't breaking rockers. But then I go from a $65 set of rockers to a $400+ set of rockers. And again, where does it end? Bigger lifters for all? Roller lifters for all? No lift rule?
