Replace the engine head with a good used unit, or remove and send damaged head for repairs.

As unfortunate as this news might be, I would prefer to stop working in a frozen garage haha.

I will still wait for the borescope to arrive and do a few mundane tests before calling it. Besides the head gasket and intake/exhaust gaskets, are there any other gaskets I should order/prepare for? Maybe valley pan gasket while I’m there?

Thank you!!! And happy holidays.
