my stage 6 mw heads were not cnc ported , so chapman is wrong , but i had dave story of story porting in crestwood , ky . he did the porting though my cam grinder/builder . dave claimed well over 300cfm in the intakes side . my question is , are these stage 6's mw ports pro ported enough to feed my 540plus street engine and turn 6500 plus ? or should i rethink the heads ? and why are trick flows not in this discussion ?
