A crack in the combustion chamber would produce pressure (compression) in the radiator, and coolant out the exhaust. There are some diagnosics used to check for combustion gas byproduct in the coolant. I believe it is some kind of test strip. Many current production imports make retorque a requirement after head gasket replacement. If it was mine, I would retorque the head. It won't cost anything but a little more time and an oil change.

Good Luck,
