As a matter of historical fact, when NHRA allowed any stock appearing valve spring, it was shortly followed by aftermarket steel retainers, ceramic lifters, tool steel lifters, oversize pushrods, oversized studs, and now, roller rocker arms. And stockers than run 8500 rpm in the lights. I don't believe that is what you are looking for with Pure Stock.
