Basically a ralph motor
Rich,
Maybe ralph will chime in. You'll pretty much have his,and bob sebrowski's motor(s) if you do that. You have His e-mail. Don't hesitate to shoot Him one on this question. Ralph's a great guy,and will lend you a hand if you need it.
You're definitely a car guy...:) You just put headers and a new chip in,and you're ready to tear it apart once again! :thumbs:

Correct me if I am wrong but I think the ZZ-4 heads are the exact same as the L98 D-port aluminum heads.
What does your car put out right now. We could take more of a calculated guess if we know what you have as a base number. YOu are probably at 300rwhp with the 219 cam right now and I say with AFRs you add 30rwhp.

Re: Afr heads (corvette0096)
(cc) Port Vol intake exhaust (cfm)
D-ports 163/58 186 152
AFRs 190/64 236 163
Just look at the intake cfm comparison, you should get 25-30rwhp. I'm assuming the zz4 d-ports are exactly the same as the corvette d-ports though.
