Yes- and/or the lifters. When it came out about 10 yrs ago, the idea was to 
deliver a little oil right at the point of max load on the cam-lobe nose, 
even though the hole actually oils the whole periphery of a lobe. The 0.020" 
hole in all 16 lifters apparently doesn't cause much of a pressure drop;   
I've not used them. Nowadays, builders also began using the same EDM idea to 
deliver oil from roller lifters to one or both ends of roller cam axles. All 
for reliability. Anyone using either solid of rollers with these oiling 
holes? Curious- J Deryke
