Hello I will help you with your question,
The intake and exhaust lines go up, if you look behind the cam gears on the cam cover you will see a notch for each cam gear to line up with. Not the best place for them but that is where they are.
Let me know if this helps
The crank mark is on the bottom hidden behind the gear on the oil pan. I bring the mark out where I can see it with a paint marker.
The line on the cams is to the left of the intake/exhaust marking as you look at it from the belt end of the engine.
The complete procedure is below if you don't have it already and you can see as much as Suzuki ever produced.
