"As long as you go with good roller lifters, with pressure-fed oiling to the needle bearings, there's no reason a cam that's mild enough to run those low spring pressures, can't last 100,000 miles."

And if I remember right when Highway was talking about that, he was running very mild spring pressures......like hydraulic roller type spring pressures, which is why he got mileage out of it. So it had to be a very mild solid roller lobe profile.
