Am I getting warm?

I believe the new approved cylinder heads are the 5.2 Coyote, GT350 cylinder heads. They are CNC ported and also have a larger valve.
They also have larger port runners.

The earlier heads are hard to find just like the SBC so these are the superceded heads. Nothing to look at here.

That is not what this is about, at all. No new heads were added. Some were taken away that shouldn't have been there to begin with though.
