Match this 500hp/500lb-ft Combo?

Ported facotry iron 'I do typically' will end up in the 177-187cc int port range w/260-280cfm by .5-.55o lift with big .1-4oo numbers usually 240's cfm by .4oo and kick the door down into the 500's hp. Its work. Today's heads while a step foward..arent that impressive to me. Mopar still yet to get a head that touches [email protected] ootb like some SBC afr's n others do.
Makes no sense they haven't slotted holes or fiddled locations to get it done...for the sake of osfa I guess.
