I would think that if valve float didn't limit the RPM before 3000 the next thing to go would be the crank. I'm not worried about the babbitt. But there is a lot of weight reversing direction twice a revolution. I'm talking about an engine right off the assembly line, not a modern rendition. But your the expert on these engines. I just feel that Henry never intended for them to be turning that high on a regular basis.
