Hi Mike
I wouldn't hesitate taking the crank down 0.020 and using it that way in a street driven or weekend drag strip car.

Not unless someone had it done after it left the factory.

Progress! That's always fun. Post a picture when you have the engine assembled.

I don't know about the valves, but I do know that if the engine was well cared for you could have one that old without it being apart. Years ago I had a 1970 Cutlass with a 350 engine that had over 250,000 miles on it and didn't burn a drop of oil. When I bought the car I got all the service records that went back to about 60,000. Sadly the car got crunched when an oncoming car lost control and came sliding across the centerline at highway speed.
