Default what caused this?

i got a set of 241s awhile back when i bought an engine.. never really did anything with them. ended up selling the engine and was thinkning about selling or using these but when i looked at them i realize these marks by the exhaust valves.. looks like they were rubbing but valves, seats, guides look fine.. no valve springs so valves could have been changed but dont know...what do yall think?

Id say your valve guides are toast.

Looks like nothing if you are referring to the clean spot next to the exhaust valve.
