I just gotta know what they flowed. (without the golfball too) Dave
Your PM capacity is full. Sorry. I was asked not to publish the flow numbers just yet.
I didn't know my box was full, cleaned it out a bit. I understand, if they don't want the numbers published that's fine with me. Thanks, Dave

Send them things to Modern put the 500" together and then run with the DDS 
4.89 in a 2,600 pound car in the 1/8 mile, is that doable with a 500 inch motor.
You're not helping Scott.

I'm writing a book "How to Build a Max-Performance Hemi" for CarTech books (The SA series). Chapter 5 is all about the heads and as part of this book I took all the familiar heads and flowed them. I even did a BAE head just to see what those monsters would do.
Anyway - here what the MP (cast iron) and the Stage-V head did. The MP aluminum head was just a shade less than the Stage-5.
No port work.

Will there be a chapter on valavetrain geometry and how to set it up ?

Of course - it's one of the most important things about building a Hemi.

I finished assembling the Hemi for the book last week. We flowed the Stage-V heads after a bowl blend, gasket match and a minor first stage porting job. Angie at Mopar Engines West did the work.
They flowed 400 (int)and 280 (exh) at .700 lift! I was surprised.
Dyno next week!
Cool, that was what I was looking for and plan to do to mine, for the 426 build, port match and some blending and if I get 400 cfm I will be happy. When I build the 528 I will send the to get CNCed.
