One down side to a roller cam is the roller on the lifter develops a line load and a very high surface stress, and this is in the best of conditions with a smooth contact surface. With a surface roughness that is too high, which appears to be what you have on your cam, your peak stress values are likey through the roof and the cam will start breaking down.
