Look forward to hearing back from you about the porting. I also have the same question as a member asked earlier in the thread. What type of compression am I looking at with:
a 347 CI
6.125 rod
3.903 bore
3.622 stroke
-4cc piston
6.0 gasket...i believe .052

The number I come up with is 9.2:1. This assumes a zero deck height.
I am still awaiting the costs from the porter, but I will still grandfather in the price wince you have already made contact.

Thanks,

Last day for a great price for 317 heads with new LS2 valvetrain.
Going to be $150 more on Friday. Call our shop and ask for Tim if you want to get a downpayment on these today.

The porting which would be deep bowl work in the intake and a fully ported exhaust will be $750 extra. Give me a call if you want to get this order going.
