Are you sure, it's not comming from the Plug drain holes. There are no high pressure oil passages through the head joint ony drains. those usually get sealed by the paint on the gasket. You did re paint the gasket , right?

I'm having a hard time imagining how this could happen. Unless you damaged the head surface when you "Flattened" it. Exactly how did you go about that? Lapping on a solid flat surface is the only way to do it right. If you used sandpaper or anything besides free media on a good surface, you may have ground away some metal needed to make a seal. Like I said, there in nothing but gravity pushing oil through the head joint. Did you check the High pressure lines in the back.
