Sorry about the typos and big pics. Posting from my phone.
The ledge below the seats will be blended with the port. Supposed to be cold here for a spell so we may be delayed on the block work.

Very nice work Butch... I presume this is set up in a Bridgeport end mill?

Glort,
As much as you are here you must be aware of the potential problems.

I have a single and a twin. The twin got a total rebuild from new. The single I
must have been lucky as I basically "put it to work" with no more than a good
checking over.

The single has at least 100 hours on it. The twin probibly less than 50.

I would not trust either one long term. They both run fine with little vibration and
no problems. For some reason I expect either one to blow up at any given moment.

I also have a Chinese diesel. It is a "changfa" clone. The thing rattles and bangs like it
will let go at first run. It has always started, runs a 15kw st.head and powers my home
when needed. I don't really have much faith in it either. It probibly has a couple of hundred
hours on it with no problems.

I guess I am  skeptical of any of the clone engines. I haven't had any real problems with any
of them but I always have this lingering fear they will blow up at any time.

My favorite engine is a Mitsubishi 3 cylinder from.the early 80's I got on a deal for next
to nothing. I have it coupled to a 7.5 st head and it runs great. That one I I don't fear as much.

Mitsubishi S4S licensed to Lister/Petter and turned out on the L/P Americas Kansas assembly line as a DWS4... arguably the best modern Lister engine available. Perkins, Caterpillar uses this same exact unit - 804D and 3044 nomenclature. 26 units remain available.

Great details on the valve and seats- you are a great tech writer.
I have a few questions on valve guides:
How is the knurling of the valve guides done?
How do you check clearance to know that needs doing?
Could the originals still be used after driving them out of the head?

Thanks for details on the knurling and fitting of valves and guides!
