ACCEPTABLE CAMSHAFT WEAR?

[Rick Allen]

In the process of rebuilding my R2 engine, I ordered all the parts except the camshaft so far.  I was told by a respected Stude engine builder that the camshaft very rarely wears out and needs replacement, baring any catastrophic failure.

That being said, can anyone venture a guess as to what is an acceptable wear difference (in mm) from lobe to lobe on the camshaft?

I should add the engine/camshaft has 57,000 miles on it.
