D311 head info and options

Valve seat inserts are available. Says they are for the 4F1599 casting number head but I don't see why they wouldn't work on others. Part # 1H0230 for both Intake and Exhaust. A good head rebuild shop should also be able to do the repairs and probably source their own inserts.
If hp is a concern use the original 212 injection pump set up.
Check the difference between your oil pan set ups between the two engines. May be a difference in oil pumps and scavenge arrangement.
The manual your looking for is the "Servicemen's Reference Book" for the 4" bore diesel engine. Covers D311 Industrial, Electric Set, Marine, D2 Tractor and #212 Grader.

On a 311 its important to maintain valve height because if you recess the valves to much by just grinding the seats the decompression wont work.

Have fun with the grader, I think it would be fun to run one.

I have a pdf of the D311 serviceman's manual, pm me with an email address and I'll send it to you.

Moog, Going Thru my Cat service stuff, I found a Valve Seat Inserts Section. For the D311, Head Part#- 4f1599 uses a Valve Seat insert Size of 1 3/4 x 1 7/16 x 1/4. Cat Part #1H233 for both inlet & Exhaust. I will try & scan the page when I can, Ken

Yup,dropped a line reading part number 1H0230.
Correct number is the 1H0233

I would clean up the cylinder head and check for cracks before getting machine shops involved with valve inserts, any cracks will be easy to spot from the seat area to the pre chamber thread.
