Are new head bolts necessary when replacing head gasket? Couldn't find anything in the service manual so I'm assuming i'll be fine. Thought id ask to make sure. Machine shop guys said my heads were warped. Putting my engine back together, just painted my block today. Going to start bolting stuff back on tomorrow. Going to buy the CZP 550 Zeros, they'll be in stock in a week or 2. Don't want to forget anything. I also need to fix my steering knuckle thing beat it up pretty good getting it off. They are $400 for a new one. No thanks
