Top end refreshment
Trigger:
If there were no noise from the bottom end, leave well alone. What i would suggest is take the sump of to clean it out and check the mesh filter is in good order. While you have the top end of you may as well check the piston ring's and as i can see the head is in need of an overhaul. Oddjob must have bloody good eyesight or a better zoom than me to see contact marks on the valves. I would not like to make that judgement without seeing the head up close and personal. Any bent valves would need replacing and can be tested.

At the moment only one nut has copper washer which is half broken, would you say that I should replace it with steel washers?

Thanks for suggestions and comments so far.
Here comes another question.
I cant find any local soda blasting place, so far I found a company which uses plastic mixed with glass, can anyone reccomend using it?
They reckon it works same as soda and they will mask off whatever needs to be masked.
I would like to have cylinder block and head cleaned off, should I ask for the carbon deposit form inside the head to be cleaned too, or just the outside.
Thanks
Trigger:
Yep, see what you mean now oddjob. I was still half a sleep when i had a look. Too clean for a carbon area.
bomber:
I took exhaust valves today and they look straight, struggling with taking valve stem oil seals, how would you take them off?
I've cleaned outside of cylinder block, but there was still a lot of sand and some of it got inside, I think I will not worry about this now and just change oil twice shortly after rebuild, what do you think? is this going to screw bottom end?
There is a bit of rust on the studs, do you think they need replacing?
I still don't have micrometer and used vernier to measure quickly pistons only one of them seems way out it seems to be 58.5mm while max serviceable limit is 58.35 but not sure how precise this measurement is, I also tried to measure ring end gap and it was waaaay over what manual indicate.
I'm wondering how to measure precisely inside of cylinders, I'm guessing that vernier is not precise enough.
Admittedly I'm way out of my depths...
And lastly on all images and in both manuals I got there is a single mark for the "timing mark" I have two super close to each other, would you say that the way I took picture, is correct position to set timing and valves of course it need to be 1and4(for valves setting) not 2and3 as in my picture.
