I was designing something and do not currently have a 12A to take a measurement off of. I was wondering if anyone could get the center distance of those studs marked by the red line. Or from outer edge to outer edge of the secondary ports marked green. If someone could get those measurements for me it would be greatly appreciated. I have searched the internet far and wide and cannot find anything on the measurements or design of the intake flange. The last guy who asked about a drawing of the flange got told to just buy a gasket. Why is the intake flange such a huge secret??? Theres plenty of CNC ones and somehow theres nothing online???

​​​​Sorry about the mini rant but getting the measurements would help greatly. Thank you.
