This is one of those tasks that require the right tool for the job.

Something I did yesterday.....I have this old Kohler, bit of a rod knock sound, I replaced it with another engine. I took the old rod and plastiguaged it.....005 clearance, where there should be under .002. I took the rod and rubbed it on emery cloth on a piece of glass until I got it down to .002.....Started it on a stand today, sounds good.......Gonna put it in a tractor, see how long it lasts.....

For what it's worth, I designed a cutter to run in my drill press to grind a valve seat - as I said, it ended up with too much flex and the seat was not flat. I tried it on an old block - good thing, cuz I did more damage than good...

As far as valve seats i bought a couple large round mounted grinding stones and using the same process (putting the bob in the drill and a carbide tool bit in the vise ) i set the proper angle to the stone then just mount your block or head in the drill press and you can grind the seat. you must regrind the bob for each seat.
not great for high volume but the parts are available at any hardware store
