I wonder how well the shorter 5 bearing cam bearings (especially the center bearing) hold up in a later engine block?

It seems that early cams don't wear as much, but are ground to the same dimensions. There were three 5 brg cams, the first had all 5 ground to the same size, #2 had #2 and #4 ground smaller to ease assembly in the 3 brg block, #3 had them just rough turned on a lathe.
