Thank You!
Haha yes, for my 1956 two stroke Pannůnia it would be ok
I have found the right shop making gaskets after the sample. Getting a coffee and starting the head disassembly. Wish me luck
The problem is that the radiator repair shop answered that they are not repairing motorcycle radiators

Cool

The gasket manufacturer had one gasket on stock for my bike. I will get it tomorrow.

So far so good.
Now the question is, can i support the engine at the oil pan? Wont crack? My plan is to put thick wood between the pan and car jack. Is that ok this way? Thank you!

I can not access some cam cap screws with the torque wrench when it comes to reassembly. Two which are closest to the cylinder head to frame mounting points and the one over the intake cam mid cylinder closest to the frame.

Going step by step according to the factory manual... and bang! Those two head to crankcase screws at the front between the exhausts is missing from the steps. And i was wondering why i could not lift the head. Then noticed that the back is already lifting some half mm so something is keeping the head back at the front. Be careful!
I was very efficient with supporting the engine i think With the first height setting the head to frame screws had no restriction. the thick oak plate is supported by two car jacks.
I could not pull out 3 head bolts only remove them with the head.
Also finished cleaning the tank. You can see it drying with a hair dryer Added some oil after that.
Please comment on the pics, especially on the condition of the head and crankcase meeting surfaces. Is this a common sight or very bad?
Now some problems to solve. How to clean those surfaces?
How to clean the cooling jacket and the bolt holes?
Its fun to do this repair, really enjoying it
Some eye candy:

Two more things. How to clean the black off the valves and head?
Head bolts were truly dirty. Just realized that they were standing in the coolant. However, after cleaning two of them i was surprised that they had only minor surface rust. Moreover, the threads were nice clean. I will check the others as well carefully.

Wow beautiful head gasket 😉
I did one additional thing: I took out cylinder sleeves (thanks to that cleaning of the all the engine tricky areas was easier) I checked if any of the piston rings ware seized (and they were seized, later you need to set them up as service manual is recommending) later resealed sleeves with Hylomar (you just need to mark which sleeves goes where) it is relatively easy job if you know what you’re doing. Cylinder sleeves are not attached in any way to the rest of the engine (only glued with Hylomar) You can buy hylomar in any bmw service. They got cylinder sleeves in their cars 😄
BMW part #81229400339

It’s good to do this when upper part of your engine is taken apart. Later when you notice that you have any oil leak through the piston rings or coolant leak because the cylinder sleeves are not sealed any more it gonna be bigger problem. It’s just my suggestion...
Great job so far.

Thank you very much, i was not aware of this. Sure i will check it!
Also noticed a small gap between the first and second cylinder sleeve. This is not a big problem then?

Hylomar is very hard to get here, or i am a bit unlucky because the few shops i could find are out of stock.
I have bought some toothbrushes, gun barrel brushes to clean the water mantle and bolt holes.

Have you tried at BMW dealership?
I gave you part number.
About the space between sleeves- don’t worry about it.
About cleaning the surfaces where head gasket was I used water sand paper grade around 2000 and dish sponge pads (not metal one, look attached picture) Maybe professional mechanics are using different techniques, but I’m not the professional mechanic 😄
You need to be gentle with those surfaces.
