I had the very same problem a few months ago, did everything you did, short of the head. Checked the timing about 5 times, everything, to no avail, got disgusted and parked it for about a month, decided to drive it to work one day, and wow, no more problem, actually runs cooler than it did originally, got me???
still going just fine. I was thinking maybe it had an air pocket or something, but really don't know, I burped it numerous times as well. Good luck
