I didn’t see it mentioned, and i would have to search back to your eng build threads from past, but oil pan design. A good scraper , maybe zero clearance teflon scraper. Good oil pan.
I have a Charlies pan that is very good. Uses a big screen. I tried a scraper but showed no gain at the track, and gave up trying to stop it from leaking. I would assume the next move would be to a dry sump but i would have a real problem packaging that with my current setup.
