Here is my headgasket with studs.
I've got the head bolt I tried to retorque. You tell me they can be retorqued? I don't believe it.
When I go to work on tuesday I'll grab it and get you a picture. If your lucky, you've been wrenching long enough like I have and knew something was wrong and stop before it breaks. If not...you get to pull the head and start drilling. And I hope you get it right. Drilling and tapping a block isn't fun.
