head issues

[JET]

Why bother checking it when it is warm? If it is bad, it is bad. Let me know when you get the head pulled off. I have only seen DSM headgaskets blow from the cylinder to a coolant passage (except for my metal one last year that melted out the back side of the head).

Did you TDC the cylinder right after the exaust valves closed or when the intake valves closed? If you try to pressure up the cylinder during overlap it will do what you are describing.
