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.

Its like that for all the aftermarket heads! All have been treated as a separate combo.

Billy- What happens when the "aftermarket heads" get the HP hit? Does it effect the "stock head" HP Factor too?
