p.s my opinion AHFS is a result of NHRA embarrassed when we go 1-40 under thier bunny *** indexes.

Jack, I will agree with every statement that you made. All good points as usual !

I have to differ with your last opinion only. I would change it to read:

AHFS is a result of NHRA embarrassed when we go 1-40 under their bunny *** HP factors on some combos.

Also, as you and another poster pointed out in stock is the valve spring rule. That along with the massaged intake ports/chambers is what allowed the bigger gains. Either or both would be pretty easy to eliminate. The heads are illegal anyway supposedly, so no loss there. This all started when it became standard policy to change a rule instead of toss a competitor/builder for a year.
