Jerry, I've been through the flatten cam problem some years ago. I had the engine rebuilt and is still in use by someone else. I wrote it off due to not knowing about ZDDP and flat tappet engines.
When does one know when there is a flatten cam lobe? I have never established a base line on any cam I've installed. Do you read the lift specs from the manufacturer and do the math?
