SOURCE: where to set the timeing
The timing mark on the crankshaft sprocket should be at the 12 O'clock position.....the timing mark on the intermediate sprocket should be at the 6 O'clock position...in other words, the two timing marks are aligned.
The drive pins on the 4 camshafts must be vertical or perpendicular to the cylinder head, ie 90 degrees to the cylinder head surface.
