If there is down pressure on the lifter in the bore, you can't build a cam that will survive it. Metallurgy on failed cams have shown the cam metal isnt the issue. It is a lubrication issue, this forum has proven by using extreme pressure additives, the additives that survive poor flow (in most situations), you can protect that cam better.
And hardness checks of cams from engines with a wiped cam. All were high hardness (from reports I've read, anyway).
