Just seems a bit odd. Maybe as a guy whose combination was not blessed with aftermarket heads,(or intake manifold), at least for Stock, I am somewhat skeptical .

Rory, I agree with everything that you've said. They were "allowed" WITH a 10 HP penalty over the production head.
Somehow, the Mopar heads are being treated as if the aluminum head is a different combo from the OEM head with it's own HP factor. Not the +10 HP over the OEM head that NHRA originally assigned.
