Stock Eliminator Cylinder Heads

Cheatin' is cheatin'. Don't matter if everyone is doing it, it is still cheatin'. I really don't know how you hold your head up after you beat someone in a "heads up" or for "class" when you are illegal. If it makes you feel proud then go circle track racing where it is a badge of honor.
Just $.02 from a cranky old man.

If they're going to allow the heads to be taken to a certain level, I think the rulebook should reflect that, if not, the rules should be enforced.

That's why I have 70 to 80 mopar 906 heads with different casting dates. Some are just better than others. Also have several sets of 346's and 452's.
I have spilled enough alcohol to float a boat pouring runners.
And then try to figure out what works best. Its a scavenger hunt with a rubik's cube all in one. It's fun, but sometimes I wonder when the fun will start.

Chevy truck heads we got'em !

For ten years I ran a dirt track Sprint car. Cheaters, when caught, were looked down on as well. When they started to P&G the top five cars every week, we lost some out of town cars. :-)

After I built my flow bench (could not just buy a SuperFlow) back then) I was shocked at the variation of air flow between different castings, same casting numbers.

Yep. It is called "Core Shift". Caused by a deviation during the casting process due setting on the mold, mold alignment issues, mold temperatures and pressure differentials. One of the many reasons why the fast guys spend lots of money testing and going through many castings.

Main issue is the pins and bushings on the cope and drag wearing overe the course of production. The foundries don’t pay close attention to this! Been in many foundries and they all have same problem from time to time. Lack of good QC.

I'm pretty sure if you spend $6000 on a set of small block iron heads that "core shift" becomes a non-issue.

Oh but you can have problems. It’s call the lawn sprinkler problems
