What's the seats look like under those valves? If there are no impact marks on the pistons they have to be burnt but they look "chipped" to me.

please pop a broken valve and its neighbor out for pic...
The valve could simply be worn out, if you take them off is there a groove worn all around the valve face?

A popped out poppet
The less damaged valves show a smooth seat. The one under this valve would need to be re-cut for sure.
I measured the valve stem and it is right on spec throughout the length so its still good................

That valve is burnt. It overheated then a chunk broke off.Ed
To measure is to know.
