6.0 diesel heads

Can anyone tell me if the head is still usable with that hairline crack

If there’s a crack in a gas/diesel engine head, the head is shot.

@Tester is right. Even though we can’t see the picture, any crack must be fixed or replaced. There are shops that can weld cylinder heads and re-machine them.

The few times I had to have head gaskets on my diesel, the heads were always sent to the machine shop for magna fluxing to determine if there were any hidden cracks. If so in the trash.
