That would explain why there are more than a few of these in engine shops across the US:

The rule is simple you can not do any of that legally. So If you want to be legal as you say you can not get heads that have any of those things done.

In My opionion (that is worth pretty much nothing) The problem is they don't let the tech people do their job. And the cheaters need to accept the fact that they got got cheating and not run and get their lawyer. Face it any one that pays $5000 for smallblock Chevy stocker heads knows dam well that the heads are not legal acording to the rule book.
Nobody cares what is actually legal all they care is will the lack of proper tech let them run them anyway.

Wade did not come on here to be bashed. He has a legitimate concern and was very honest about his concerns. The word "legal" doesn't really apply anymore, if it ever did. As with almost any motorsports, what "will and will not pass tech" is a more appropriate phrase.
