early 40hp: adjusting screws don't meet valve shaft properly

[pastellgreen]

During assembely of an early 40hp engine I wonder why the adjusting screws don't meet the valve shaft as I would think they should and I know from the 36hp and 30hp engines. I would like to concentrate on the sideward offset given through the VW bulletin, but it isn't really possible as the adjusting screws hardly meet the valve shaft end. They nearly hit the edges of the shaft ends. For my taste, the rocker shaft sits too far downwards.
This is observed at the current cylinderheads with index "B" with retrofitted original VW short studs, I also keep the original heads with no index in their original condition an there it is absolutely the same. Also, the adjusting srews are nearly set at the end, there are only maximum two turns left.
Is this normal?

For me it should look like this:

The adjusting screw center being offset is to aid in the rotation of the valve.

Rocker geometry can be affected by pushrod length, spacers where rocker shaft mounts, as well as along shaft between rockers. Good luck!!

Did you split the case and inspect lifters? When I rebuilt my 1500 to 1600, lifters were so worn as to be concave (instead of convex as they should be) where they ride on cam lobes. This might explain your need to extend rocker adjusters out so far as to make them contact valve stem ends too low? There are engine builders with way more experience in the performance forum, maybe post your issue here:

Thanks for your input. Independend, I can turn the adjusting screw in and out, it never comes to a position I would think is normal.
My hope here is that Glutamodo or Rome come with their early 40hp experience telling me it is just normal.

are the rocker blocks upside down by chance?

will check it.
Got back today an engine block of a 1962 engine I already know and have driven for two years. I will have a close look on the situation there, as the cylinder heads are also old ones.

Today I had time to look under the valve covers of the 1962 engine. The same story, so it seems to be original like that. Only difference was, the blocks for the rocker shaft have a bevel. Perhaps they improved the alignment for the adjusting screws with cylinder head index "C".
