How many people have had a flat tappet lobe go bad soon after break-in.

I have had many flat tappet solid cams over many years and never had a single issue with any of them. Bracket raced a few in the 90's and beat the snot out of the motor. IIRC, spring pressure of 130-135 closed and 300-330 open. I now use a Comp Cam 282S and week after week valve lash NEVER changes. Engine sees 6200 rpm regularly.
