I too have noticed that the stamped numbers aren't always exactly visible, so before I take them off I always scratch in the nunber and leter into the top of the cap with a scribe so in cas eI dropped them on the flor I'd know where they go. Typically though I take off one cam at a time and replace the caps immediately so that they alwasy go back on the way the came off so nothing gets mixed up or lost. Becuase like I sai, damaging or losing a cam cap basically makes the entire head a useless lump of metal cos you cannot substitue a cap from another engine.
