I know greenbook says 0.5mm.
This one looks wider but maybe only because I zoomed in?
I think I will keep those exhaust and intake valves. They require to be reconditioned as well as the valves seats. I don't know what is the maximum size of a crack but yeah, as you said, greenbook says 0.5mm. I think there is no doubt that they are exceeding the specification, but anyway I will try to put this cylinder head back in service.
