The prelube is FOR the bearings. They're dry on startup and the cam would grind on them until oil got there. You're getting prelube confused with cam break-in period. Flat tappets need to be broke-in on the first startup and the prelube protects them until the lifters mate with the cam lobes. Roller cams don't need a break-in, but the prelube is still good protection.
I put prelube on all cam, crank and rod bearings, valve stem tips, rocker arm pivots, pushrod ends, etc. Basically anywhere there's metal-to-metal contact that the oil normally lubes. There's no "grit" in prelube. It's really just heavy weight oil. It washes out once the hot oil goes through there.
