I'm looking to run a set of AFR heads with it. Not sure if I need 180cc or 190cc. Any suggestions? Not looking to turn over 6000.

it deps. on your ci. anything over 350or355 would pro. need 195
i have seen some low reving 383s with 180s but if your going to 6000rpms with a 383or bigger youll need the 195s.
