Depends on if the C heads are big or small valve. Depends on if your looking for nothing but gross flow #`s, or which head would flow best for your particular build. For WOT, 1/4 mile cruise, big valves and all that go with it. For a well behaved, responsive, torque motor for the street, small valve. |

In my humble opinion, there`s only 2 questions that need be addressed before spending that kind of money. Are you planning on this  Or this ! Only reason you`d want those heads sitting in a parking lot 99% of there life, is so you can "jack your jaw" I swear jeffy, you`r part crow ;D  All I have is C heads, just putting out the information is all! |

I was asking my self the same question earlier this year. I have a set of A, C, and E heads . I decide to with large valve C heads. The rocket racing heads are nice but it would be over kill for I need. Read this it might help you make your decision nichibei.tripod.com/headflow.htm |

Your missing nothing You`d do better to do the correct cut on your valve job with small a heads, than a big valve head for a street car. Run cooler, stronger, low to mid range |
