I was taking out the headbolts on my engine today and the last one was rounded off. I wasn't able to turn it at all because it seemed like it was rounded off when a previous owner put it in. Cant get a rounded bolt bit on to it either. Any suggestions?

Might try the low profile bolt set. the rounded off bolt set i have now the 14mm is a little to big and i hit the wall of the head with it
