interesting thread on the cam followers.I made a jig to re profile them in the early 90's and have never had one wear like those photo's.I run the Honda valve springs too which gives you more rpm range than what the crankshaft would like.
The dropping zddp/Zinc levels in oil has been a issue here in Historic racing,oils aint oils. Seen cams and lifters chew out in one race meeting when the formulation of the oil has changed. Penrite freely give the Zddp levels of their oils. Bike oil also runs more zddp which many now use with high lift cams.
