Antifreeze in the oil. What is the torque of the engine head bolts

First pass is 22 foot pounds. Second pass is 155 degrees.

You did not say what the symptom is, so I do not know what led you to the conclusion you arrived at. Do you think tightening the bolts is going to solve a leaking head gasket, or are you replacing the head gasket?

These are "torque-to-yield" head bolts. That means they are designed to stretch one time when they are installed. They must be replaced once they have been removed. If you try to reuse them, you will not achieve the correct clamping force.

Worse, reuse them and they can snap in the block, so you get to remove them again. Remove the broken stub and replace the new gasket and buy the new bolts that you should have anyway.
