OK, that makes all the difference. That's why I wasn't aware of their cars. Those are "GT" Super Stock class cars.
Those engines go by Super Stock rules. More head mods allowed, plus unlimited roller cams & aftermarket intakes. IIRC, a GT racer posted that the ports in SS heads can be reshaped.
So, I won't even consider SS heads in this discussion.
BUT, I'd really like to know what cars those engines are in. I try to post info about all Pontiac powered SS cars that are entered in big races. BUT, for the GT cars, most lists do not post what engine is in each car. I've discovered several Pontiac powered GT cars, which I'd missed.
