Brian, you can pound salt in reguards to your "heaters" comment! My "heaters are better thought out than most $30-$100,000 Stockers.
Now in answer to your question, my DD told me years ago that he won't keep his people late on a Sunday night to be tearing down cars as most of them have already been there for 3 or 4 days and they have families and jobs waiting at home.
Chad, you don't need to just check the top10. If I were going to intentionally cheat I would run the car where it wouldn't attract any undue attention. 2 or 3 thorough random checks at a few events a year (Nat. and Div. and from all over the ladder) is all that is needed. Just the possibility of a teardown would clean up most of what you are looking for.
