Based on this how is this motor legal?

If I remember correctly the heads were CNC from the factory? If that is the case how can NHRA prove that additional CNC had been done? Short of the cc's? When I first saw several years ago where CNC heads were installed on some of the super cars that clearly opened the door for additional porting. The thing I don't get from the article is the changing of the cam, to a larger grind? How can you tell this "Stocker" engine from a "SS" engine??[/QUOTE]
In this case it wouldn't be very hard they bragged about it in a magazine article.
