I don't think so. It is definitely hard and not easy to remove material from. I also did it slow and easy, not to heat it up. It was always cool enough to touch.

Too late, its ground and I'm confident that its square. I get anxiety over small details, if I didn't think it was square and smooth, I wouldn't use it.

what was the original issue???
was this a new valve?, old valve after a seat repair??
if this was a recession issue, the repair although worked, did not solve the base issue.
the valve material is pretty much hard all they way through, UNLESS, it is a sodium filled valve which if done will destroy your engine when it breaks like glass.
yep, saw dust in the ole rear end will quite her down, at least till the bearings fail.
keep money in your pocket and the cell charged just in case you are on the highway.

hummm????
a band-aide fix
sure you can get by just like running a piston in a .008 taper hole, but, issues follow. depending upon the head setup, you could induce valve shrouding and flow issues.
your dollar but for me, new seats would be the ticket.
i will tell johnny to warm up the western flyer and oil the pedals.

I used to grind valves when I worked in a machine shop. Part of the process was grinding the tip of the stem to make it flat again. It can be done but not with the valve in the head.
I'm not familiar enough with these engines to say what will or won't work. .015" isn't much but specs are there for a reason.
I've done some shady **** with a buffing disc on die grinder on large diesel engines. Harley engines seem too delicate for that kind of thing.

Hold on... if a valve job was done RIGHT, the installed stem height should have been accounted for and set. Sounds to me like the valve seat was ground too far, which will let the valve head sit too far into the head, which means the valve stem is now too tall. I'd go back to the machinist and ask if he thought of that...
