No I do not replace head bolts. Don't know of to many people who do. Dealers will do most anything and spend as much of your money as they feel the need to in order to limit their liability.
The last I heard, and I hope Emily will correct me if I'm wrong, CCR doesn't install new head bolts. They say to go ahead and reuse them. Emily?
Look here to answer your question:
There is a mixed view on this board, but I'm of the opinion that you should replace them. In fact there are a few sets on Ebay now, and they are available from many parts stores. My thought is that a part like this wouldn't be available if it was something that didn't neet replacing.
