Progress was very slow last week. It seems I was a bit quick to say there were no overtightened bolts. One of the bolts on the casting behind the timing belt is so stuck that the hexagon socket will be gone before the bolt comes loose. I will try to weld a key into the bolt later this week. Unfortunately that means I was not able to get as much done as I hoped.
I was able to draw the all the small auxilary parts on the head, as well as the timing belt pulley. For example, that's the coolant tap at the rear bottom end and the spark plugs together with the resistors...
The assembly is shown above. The timing belt pulley with the adjustment plate are shown below.
More to follow...
