(Home) Head problem

I'v just took the head off my town ace, i noticed when you look at the injector ports on three cylinders the head as been burnt away one in paticular is burnt away right up to the inlet valve seat but the seat itself is okay. what causes this and is the head scrap or can i continue to use it or can it be repaired thanks.
