My head should be repairable. I'm not 100% sure.
A bolt broke off and cannot be removed by drilling/tapping. This is a bolt for a cam cap.
I have tried and failed to extract the bolt, and I fear the only way for me to get it extracted is to pull the head. WHICH SUCKS.
If I'm going to pull the head, I'm not going to worry about the damn bolt. I'm going to transfer everything over to the new head and be done with it.
