page xv under "HOW TO USE THIS RULEBOOK" in the rule book
On the other hand, as to performance equipment, it is the
general rule that unless optional performance equipment or
performance-related modification is specifically permitted by
this Rulebook, it is prohibited. All model, engine, or equipment
changes or modifications not specifically addressed in this
Rulebook must be submitted in writing to NHRA for
consideration prior to competition. Approval will be granted or
denied in NHRA’s sole and absolute discretion. The applicant
will be notified of approval or rejection in writing from NHRA
headquarters in Glendora, Calif.
as I read it "Blocking passage down in valve pocket prohibited."I have not seen any where in the book that says "I was under the impression" lol
