Although it does not say you can't do it, long standing Nhra policy is you have to get permission to do it first!!! So at some point did someone get permission to do it??? If so, there shouldn't be problem. If not ???

Bob,

I'm only speaking of the engines I know of. So take that into consideration when I tell you this.. But five different customers of the now closed up Gulius camp have went right through teardown with the heads in question. These teardowns started in 2018 and finished up in Rockingham N.C this year. Pictures were taken, and multiple officials tried their best to find a reason in the rulebook to disqualify them. Problem is, they fit the current rules. In fact, they fit the rules that have been in place for decades. Last year they implemented new tightening of the rule(s), in that the original bolt holes bolting the intake manifold to the cylinder head had to be maintained. That stopped the aggressiveness of the milling, as any more cutting, and the bolt hole would have been non-existent. But it did not stop the complaining. I hope this helps clear things up.
