I fully understand the intent of your statement as it has been stated in the rule book. However, it may have not been permitted however, it sure has been ACCEPTED on numerous occasions for whatever reasons.

Again this begs the question: What if my perfectly stock unmodified heads are 20 cc's smaller than the allowed SS spec? Do you modify them, look for a set of modified heads that have passed tech, or just take your beating from illegal entries?
