This is the results with new vales, still have a lot of work to do though.
This sounds like a college engineering project similar to one my son did about ten years ago, "build" an engine in AutoCadd such that it can be totally disassembled, re-assembled, rotated to any angle, and seen with any "layer" solid or transparent. His even "ran", showing rotation of all the component parts relative to one another.

Hopefully someone has a bare 400 SBC block sitting around and they can caliper some dimensions for you. Sorry I can't help, but Merry Christmas!
