Hi Paul,
I also played the gasket game two times :-p
Then I had my head examined <g> for flatness (it was OK)
And I was told to replace the old studs and nuts. If the threads
are worn, a lot of the torque goes into friction and/or the
threads yield leaving insufficient force pulling the head down.
That along with several hot retorques worked for me (I don't
think I got much after the first couple, but I was paranoid about
having it leak again!). If you're heads not better, try that.

Jeff
