Wiped Cam Lobe Theory - Imput Wanted:
I agree that oil holes in rod bearings don't do anything special to the cam compared to the oil bleeding out the sides of the bearings. The cam is already well oiled. It's a bad break-in that really hurts people's ego. Ive been there too. That's why it's so Important to pay attention to detail, follow a checklist, and have a helper during break in. It doesn't take much for lobe - tappet friction to runaway and to the point where you've lost hydraulic preload and that tappet is getting hammered more to death.
After break in, it's important to remove that damn valve cover at idle and physically watch your lifters and pushrods spin. Break in May have been successful but if they don't spin or spin poorly, it won't last very long.
