Looks good. A couple of questions/requests.
1. Runner volumes
2. Bench used
3. Can you flow them on a 3.9 fixture?
Thanks, and keep up the good work.

Yep, I did make a typo, my bad. I corrected it know, thanks Chris.
These heads were flowed on a Super Flow 600
I will get you runner volumes in the next couple of hours. Also the chamber sizes of unmilled heads. We basically can get you chamber sizes from 68cc down to what ever you want to mill them too.
I will try to get them on the bench tonight with a 3.9 bore and will give you the results as soon as I get them.
Thanks for all of the questions.

WOW, absolutely amazing. You guys keep pushing the envelope, and the communication and customer service are second to none. Congrats.
I know who I'll be talking to for my next motor.
