Don't know what causes it, if you ask cam supplier they say 99.9 percent cam failure is do to improper break in, others say poor cam.
There has been some discussion in another forum about the changes in oil formulation and that most, if not all the heavy metals (basically zinc compounds) have been removed as the new engines with steel camshafts and roller lifters don't need the same protection as the cast cams. Some of the Diesel oils have the zinc - i.e. Shell Rotella. You might best check if Valvoline racing oil has this additive.

Also, you might want to consider low poundage ("loose") valve springs and a less aggressive rocker arm for break in. Camshafts with a fast ramp are prone to wear fast without some good break in time.
