They might find something you overlooked, but you better have had some pretty good sleight of hand if you went with bogus stuff.
Who do you send your heads to? Who will have the data files NHRA uses?
Do the engine builders need the same equipment as NHRA? If, and it's a big IF all of this speculation actually applies to "classic" stockers (old stuff)....I'm not sure it does. But if an engine builder that builds older combinations with old castings isn't really cheating the heads....I'm talking grinding and spray welding....he doesn't need the equipment. He won't have access to the data anyway.
My opinion.....You know what's real BS? Thinking that core shift or old core boxes will cause a head to scan as illegal. If the head was that bad would it even run well enough to need to be torn down? Would it even cc correctly (small enough)? Wouldn't the engine builder have disqualified the casting before it ever got that far?
Question for those out there, are there still heads around with altered casting numbers? It happened in the past.

Great Post !
I remember an intake manifold for a Ford CJ 428 that weighed 10 lbs less than a real stock one......And I remember an intake manifold with an altered casting number just a few years ago.
