You need to study the rule book.
Lunati and a couple other places make the stock replacement cam for the NHRA Stocker class. The stocker class cam is like 460 intake lift in 470 exhaust lift and any duration.
I think roller rocker arms are allowed now. And you can run stainless steel valves in place of the old tulip valves. There are several changes that are allowed that are considered stock. Basically I think the new stock class is the old super stock class.
Is the stocker class the same as pure stock drag racing? I'm thinking that the last rule book I saw was 2022 and it said that roller rockers were not allowed and valve's had to be same as the factory used. I'm going to look for the 2023 rule book
