440source Stealth head review and flow numbers

My numbers for ootb Ede’s are close to what he got.

I’ve had one set of cnc’d stealth’s in my shop, done by mch back when Jeff was still alive.
Those had the chambers ported and his valve job and back cut.
They flowed about [email protected] on my bench with very good low/mid-lift numbers.

The ones in the video have the std stealth valve job and untouched chambers.
