In talking to a couple of Super Stock cylinder head guys, who do heads for very fast cars, I learned that they have found things at 36" or more that were not possible to see at 28".

You may take that for what it is worth. I know them, and I know how fast their stuff is, so I have no reason not to believe them.

We can just agree to disagree. I respect you. And I respect guys who build fast cars.

But I'll stand by the fact that the square law of flow vs pressure difference is an unarguable law of physics so long as the port flow is already fully developed.
