Are refering to a tool or a graphic of how all the timing marks align.
Only tool is the cam alignment tool and its nice to have (I have a set) but isn't required.
As for the diagram of the timing marks you can get them from any manual and they will probably confuse the $^&* out of you. Top dead center #1 alingment marks for each cam/head is set perpindiculer with the respective head as well as all black links on the chain will match up to each pully/timing gear. The gothch is the tone ring some are generic and have two key ways approx 135 deg apart you pick the wrong one and youget to take it apart and try again. So when you dissassemble mark the tone ring.
