Explain to me again, please

You only have to go back to 1/15/2016 on this site to see my post about this topic , one can clearly see that NHRA has implemented rule changes that changed everything in the valvetrain but the lifters , lifters the became the weak link , many racers not only have told ,and showed NHRA over ,and over again over many years ,not weeks or months for years now the destroyed engines ,pistons ,cams ,and lifters costing racers a lot of money needlessly , if they would have left the rules in place on the valve train in the first place we would not be waiting months for ordered lifters today !

Most don't want solid roller cams in stock, just go back and read posts about it in the past. Opening up that box will get you one more step closer to making a stocker engine a super stock engine with a lift rule.

Then put the rules back ,and most will wine about that , in case you haven't noticed stock is already Super Stock ,the lifters will not change fact that stock has gotten way out of hand ,you stated Open up that box will get one more step closer to making a super Stock engine with a lift rule , well, you and others better look again if we are only the lift rule away if we change the lifters what about the other enhancements to stock over the years to get us all to this point ,You freely use the word most ,would they be the guy's that are cheating spending lot's of money to cheat are they the ones that you call most ! The point you ,and others are missing ,and it is still the same as it was back in 2016, and even before that the old cars are at a disadvantage you ,and others may just want to see them disappear while you drive a late model race car with roller lifters ,and have others that can't aford to keep dealing with the lifter problem !

Ya piks yer kombo and ya pays yer dooz.

If you want a roller lifter combo with EFI then that's where you start.

Maybe we need a poll because MOST (from my outlook with all the new motors available) are already running solid rollers. They wouldn't need to vote. It looks to me like the only ones not running them are the cars from 60-early 80's. At the rate of $2100 a set and 6 months wait time for tool steel lifters they can lower the entry to 30 and 95% will be roller motors. If I have to qualify for a event spot against a non-vin, state of the art, factory made race car at least make it fair for the old flat tappet cars.

Soooooooo.......... you don't care about qualifying being "fair to the old flat tappet cars", you care about it being "fair" to you!
Here's a "fair" way to make this work without affecting anyone else, why don't you go and buy a "non-vin,state of the art, factory made race car"!

It's thinking like THIS that has S/SS in the screwed up state that it's in and why there needs to be some re-thinking and some back-tracking of some of the rules by NHRA and Tech.

I would think a rule change would effect "all flattappet motors. Am I wrong to think that?

If for some reason NHRA elected to change this rule, I would say "either or". Some motors may not like rollers, depending on the design of there flat tappet existing cam etc.

And that's an awful lot of flat tappet motors. What kind of an effect do you think that change will have on the rest of the motor? What else will need to be changed to take advantage of the ability to use more aggressive cam profiles without breaking a lifter or wiping a cam? Not to mention the higher RPM capability.
What we need is a valve spring rule.

Bingo. More separation for Stock and Super Stock.
