You might want to get the factory shop manual if you are going to rebuild it you self. I'll agree it's not rocket science but there's a lot of goofy torques and color coding that you'll run into. My favorite is "Torque to X plus 40 degrees". You'll find those on the rod bolts as well as the head bolt.
