Grinding exhaust valve stem

I'm slowly getting what I need to finally take care of the alleged exhaust valve issue on my HMSK-80. I still haven't even pulled the valve cover to check clearance but hopefully will have time by October.

The question I have is I recall someone on the forum setting up a jig made out of wood to hold the valve and then he used a drill press to grind some off of the stem.

What bit would you use for this? I'm thinking something like McMaster-Carr 4919A531 or 4919A561

I've got a decent drill press (1930s Canedy-Otto 16") and a sliding vise is finally coming for it today so I'll actually be able to use it.

I know some guys just go over it with a file but I like the idea of using the drill press.

If the clearance is fine when I check it, my alternate plan is to put a Honda GX-200 I have on the Ariens. I'm hoping it won't come to that though.

1999 Ariens 924108 824SLE.

Chris: I'm just a beginner, but will pass on what I did. I ground a valve earlier this year, worked pretty good. For the jig, I clamped 2 6" lengths of 1x2 together, and drilled a whole between them, slightly smaller than the valve stem. I then "clamped the valve in between the 2 pieces of wood with some screws. I was able to use the edges of the 1x2s to rest against the miter gauge on a disc sander table, and gently brought the valve stem end to the sander. It worked really well, the new ground edge was square to the stem length. (though I must admit, I'm not sure if the ground edge is supposed to have any taper to it). I just went real slow, made sure the stem never heated up too much, ground a little, install and measure, ground some more, etc.
