Take it up a steep hill and see how it goes. If it's a haze, you're ok. If you're cropdusting, it's more than timing. Do the compression and leak down test.

This is the one I bought. I believe I offered $180 and he accepted it right away. It’s got everything you need and works well. I did spend a little bit of time with a file and some emery cloth to get the magnetic pickup going into the hole easier.

The probe itself was actually oversized a bit (about .005” - .010” over 5/16” iirc). I had a spare front cover on the bench to play with too, and with the hole perfectly clean, it wasn’t going in. That’s when I decided to start measuring. I figure the tolerances on the Detroit’s these meters were meant for were pretty loose and it wasn’t an issue. In reality it may be a 8mm vs 5/16” thing.

I bought the same one but haven’t used it yet. Mines running good so far but I figured it would be a good tool to have. I intend to check timing this spring when it warms up a bit.

This happened to me- lots of blue/white smoke up a steep long hill- and the cause seemed to have been air intrusion in the fuel lines/around the fuel heater. Got new lines and gasket around the fuel heater and no more smoke.... well, no more blue/white smoke at least

I have one of these as well. Yep you'll have to grind down the magnetic pickup to get it to fit. I used a bench grinder and fine sandpaper to remove any burrs.

The DTI timers are luminosity probe only, aren't they? Do they have a pulse pickup which clamps on to an injector hardline?

They come with the pickup that clamps onto the injector line.

Update here:
Replaced CDR valve and it still seems to have that slight amount of smoke when gassing it, it's possibly a little better now. I performed a combustion gas test on the Rad and it came out fine. I also pressure tested the Rad and that came out fine.
Still have not performed leak down and pressure test of block.

I want to pull the valve covers to inspect the rocker arms, springs etc. If I pull the covers do the gaskets need to be replaced or can I re-use them?

You can re use them if they are still somewhat soft. They are usually rubber. . You can run it with the covers off if need be. Doesn't get too messy. Oil will build up at the drain hole though.
