I am new at this question. Does the indentation on the face reflect a bad or going bad valve?

What ever this thing is it need help and you would send the whole head out. Why an indentation? Build up of carbon, odd collision with something - you didn't expound.

It should look like the others you didn't show - do they have the same offset indentation? Then because it's an exhaust valve maybe it's on purpose to control heat? If so it would be an indexed part meaning installed only in that exact position.

This work isn't for doing without knowing why your are at this point at all in the first place and apart now have lost that chance.

Send this whole part out and if a "V" or dual head engine the other as well to a machine shop and get it back all ready for the rest of putting it back together,
