1989 190E 2.6L Timing

[Larz]

I'm putting the cylinder head on the engine, and can't find good instructions on how to set the timing. Does anyone have any good pictures? Or can someone tell me what numbers or notch to set the crank to? Also, the cam is supposed to be set to the notch mark. But there's three of them! Two are fat marks. One is this skinny little sliver. If anyone has a link to some good pics, or to a good shop manual, please share. Setting the timing is all that's holding me up on this engine. My friend printed out some pics from his work, but they're too vauge, and the last thing I want is to do this twice. Thanks in advance.
