Yes you can run the pinto. We may have several one of a kind cars and that's fine.

If I'm reading correctly the pinto with the esslinger head would get a restricter.

Yes some of the cars like this pinto may be subject to a restrictor or some additional requirements. The engine's that don't follow along the normal D2 requirements can race it just may take some case by case adjustments to ensure we are keeping the competition level as possible
