What Doug said, unless some former owner stuck in a piston with a higher crown or compression height, or put in a stroker crank? With those a cylinder base spacer is needed. If you found two paper gaskets it's most likely as Doug said. If one was any kind of metal then it could be a spacer.
There was just the paper gaskets. I wonder if a second gasket might have been added so that new rings would not bump into a ridge? The cylinder had a slight ridge of about .001".
