Brian, coincidence or is there a reason that this would become more (if not completely) evident only after rebuilding the head?
I suppose that I could take a stab at saying the crankcase oil and vapor might have passed the valve seals on the old head.........and now, all of it goes via the breather..........but, that would be a stretch of the physics.
Are you sure that it was not present with the old head? I'm not.
