main bearings

[mackaman64]

hey just pulled down the staz`s engine and found hone marks still the bore, some stuck rings, good looking bigends but the mains are a different story,
all but the thrust bearing are good!
bearing shows signs of lack of lube scuffing and galling around oil holes?
don`t know if it`s because it`s a non full grove bearing or it`s been run low on oil,crank looks ok so signs wear etc
options?
