the bolt do not have washers already built-in. The newer style bolts do not need washers....Also, while you are removing the head, it may be a good chance to replace the fuel injector seals. They are cheap and most of the stuff around them has to be removed anyways. The little hose between the engine and the water pump and/or any rubber hose connected to the engine/head. They do get hard with age...
