I get why the lapping-stick is frustrating.. pfff.
Anyways, in the end I found a rhytm and got a nice silver finish on the valves and seats.
Even more frustrating is forgetting to fit the valve guide rubber seals, and having to fit 12 valves instead of 8. Especially without the right tool for it.
Anyhow. It all worked.
Fluid level was nice and stable after doing the leak test again.
Thank you all for the advice given!

Just picked up the cylinders. Now it's getting real :-X
Nurse Julie:
Looking good 👍👍👍 A question, why have you got brass screws on the manifold rubbers? Will the brass not be too soft to get a decent tightness to avoid air leaks?

Well, simply because I had to destroy the original screws when replacing the rubbers, and I inherited a bunch of very pretty high quality brass bolts from my Grandfather who was a fine instrument maker (not the music stuff, but metal working). The right size was available.
The tightness is no issue at all. It's 'normal' tight. There are 15 turns of thread in use, so not worried about that.
I guessed the advantage of using softer screws (instead of hex-bolts from the DIY store) is the possibility to get the bolts off again without destroying the cylinder head, should it ever be needed in future. Less risk of damaging thread or getting corrosion.

Fair enough.... Your Grandad would be well pleased I'm sure.
