Ok so as some of you may know i was considering the assualt 210cc heads. I called them up and they said that head flows averages 256 int. 197 ex. @. 600 lift. First im guessing i can run a matched duration cam with this head right? Second What kind of power is this head capable of? Im looking at 10.5:1 cr in a 383. Its a 64cc head.
