    Removing the heads. Taking off the valves replacing seals etc. Depends what motor looks like inside might as well do everything, if it looks good seal it up with new chain and gaskets since it's open.

    I have never done it on a Cadi, but w/ the right tools, valve seals can usually be replaced w/ the heads on the engine. Just, if the guides turn out to be worn, the heads must come off.
