Burnt valve?
#2
Lay a straight edge across the tops of the valve stems. Is that one higher than the rest? Or not.
It could be an artifact from previous valve job work or it could be toast. It might be a replacement valve unlike the others.
Regardless, consider it suspect.

I would recommend taking them to a reputable machine shop , and going with whatever they recommend .
To my way of thinking , I would install new hardened seats on all exhaust . and replace all exhaust valves .
Intake valves may also have to be replaced if the " margin " is too narrow after grinding .
The guides should all be knurled and reamed .

I got a great deal on them and a port o sonic intake, they had double valve springs and adjustable rocker hardware, crossovers blocked, must have been a big cam.
I have a fresh set of c heads so they will head to storage, thanks for the help.

Looks like water has been sitting in it. Actually does not look like your typical receded valve from unleaded fuel. Might have been sunk in and someone tried to save it with a valve job instead of putting a seat in it.
