Hard to say from the angle of the pic on the block. The crank will be salvageable...they can generally be turned .030 under if need be. The scratch may polish out...your machinist will have to be your guide. Valves look pretty good but if it were me, I'd have the shop check the angles on the valves and seats for true. Better to build it right first time around...it's usually cheaper that way. Whether or not you can reuse the valve springs will depend on your cam grind. I reused my springs last time around and they were shimmed a little. This time I'll likely go with matching springs to go with the cam.
