02 250 Head gasket leaking?!

Just did a top end on my buddies 02 250R. He had the head milled 40 thousandths when he had the jug sleeved. When I was putting the head on I noticed that the head gasket didn't fit... like I thought that it should. It now weeps from around the top of the head. Not a ton of coolant, but some. Everything else is kosher. The bike rips.

Head not true? Bad/wrong head gasket? I am going to pull the gasket today and see if maybe I put it on upside down?

I think I just had it on upside down? But then I found this.... -


Ordered another gasket. Head is true.
