Valve seat stones sizes?
Just to close the loop (and gloat a little), I picked up the Sioux Valve and Seat grinder setup I found on CL locally. It is in excellent mechanical condition. The seller said the original owner disassembled and cleaned it after every job and after he got it, it was used in 1992 for rebuilding a Kohler generator engine and has been sitting since. Comes with a few nice accessories that still have the cosmoline on them as well as a good bunch of stones and arbors. I'm hoping the rocker arm attachment will work on 273 style rockers but if not, it's still a cool piece of kit. Maybe I can sell or trade some of the extra stones on some larger ones for intake valve seats. Oh yeah, I paid $250 for the entire setup.
