Yikes! No orientation marks on the cams at all? At this point, I would find a set of new or closely inspected by someone knowledgeable about cams in general used cams, buy a new chain, and follow to the letter the installation instructions contained in the Bentley manual. And get a new timing belt and tensioner, just so you don't have to mess with the whole cam thing anytime soon. You said you are in California. Where? I am in El Cajon, and would be willing to help you out if you're close enough.
