Default Broken Ferrera valve

Pics are crappy but I think the damage is clear. Springs are Comp 921's and are fine. Put a hole in the piston and the cylinder wall is fubar.
Engine had 63,000 miles.

How many miles on the springs?

How did you verify they are "fine"?

Springs are NOT broken.
I have not put them on a spring gage yet but will do so sometime.
They have about 3000 miles on them 90% are street miles.
