Sounds like time to pull that head - since the tin is off, should be
pretty quick.  If it doesn't turn out to be something very obvious -
check the sealing surface around the head to cyl.  I've seen heads
that were run loose burn a hole through there....or might just have a
bit of carbon build up bound in there from being loose, and just need
to clean it up and bolt it back down.

Of course, there's the obvious - holed piston, cracked/dropped
valve/seat, or cracked head.   But maybe a cracked ring?  Seeing
excess blowby?   anyway, sounds like getting the head off is going to
be the next step.

gl!  hopefully a clean and retorque will do the trick. :)
