Hey RZ@D, thanks for joining the forum. I didn't even know about that head. Are there any out of the box numbers?

"out of the box" the heads are rather crude - they are a casting made to be cnc machined, and as such the ports are really small & the chambers have alot of material that would hinder flow around the valves.
