Why do people think the head will be warped? It didn't overheat. I don't get it. Anyway, that head is repairable, probably just with a Dremel, the piston is fine and you need new later style chain guides with the steel insert. Should be a cheap fix if the head is OK on the combustion chamber side, you don't show that in the photos.. I don't think you can use new buckets with an old cam, maybe you can get a used one, I have a few.
Mine was a little worse.......

It's a 12 xjl 5.0 supercharged. The cam is removed and it is on the exhaust side. This is a pick with the cap over the spring removed (it disintegrated). Tbe spring is out as will. This is from the top side of the head. Valve is bent and that's the only thing that stopped it from falling in the cylinder. I will take a pick with the cap removed from the other valve next to it.
What did you use to add the picture?

Not that I can remember and I have been here over 10 years.
I have never seen that type of void and spring failure on anything ever.
So I think it was a manufacturing defect and is very rare.
Or I sure hope it is!!
I do find several heads on EBay?
Here is a drivers side one for around $700?
5.0L Cylinder Head
Says only 31K on engine and has the 8mm chains.
Here is another one?
5.0L Drivers Side Head
So I think you can find one without too much trouble?

It looks like the spring punched a hole through the valve spring seat.
I've seen a spring fail and the valve stem be intact.
I've seen a valve fail, head popped off, and spring was intact.
I've seen a valve fail at the "keepers" and the spring was intact.
But I've never seen a valve fail, apparently at the "keepers", and the spring disintegrate.
