The valve face is pitted, this is down to the valve clearance being too tight. These will need re facing ;)

The valve seats look ok tho! 😬

They will clean up but, if you have new valve guides fitted. The head needs to be about 300c in a oven and the guides need to be frozen to make fitting easy. The heat distorts the head a little so, a head skim and valve seats re ground. Not Cut ;)
