Yes, I've got those for all the 0.1 values. Smallest tolerance in MKP and that value I could find at the time.
Do they work? Yes. Will others sound better? Not a clue.
Since I ordered 25, I could measure them with my dmm and choose the values that were closest to the required values and put those ones in the RIAA section.

I did my own matching. In total I bought 70 2SK170's, measured Idss, and chose 2 quads, two pairs and a reserve quad and 2 reserve pairs. I sold the rest.
You can measure Idss yourself if you want, but I guess a package of 4 will be matched, so just use 2 packages as quads and one package for 2 pairs (I'm assuming you bought the PCB's from Pass diy which come with matched FET's)

With four matched fets per baggie, I'd use one bag for each input stage, then split the third baggie for the remaining fets in the second stage.
