Not a common problem. GM hotcam is budget friendly and streetable.

Not likely. All SBC after 1987 had roller lifters. It's easy to find out. Remove a valve cover and check the movement of the rocker arms.

Second, if the cam lobes were warn down, you would have a gap or movement between the pushrod and the rocker. SEVERE noise would be heard also.

Another thing, you would have no compression in the cylinders that have warn lobes.
