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.

It still begs the question.....with the rules more laxy dazy, why are they still choosing 670 heads with all the other options that are out there available to them?

That's why I brought it into the discussion.
