I checked contact patch and they were all perfect. I was thinking cam issue as the same happened on previous rebuild with same cam supplier & new OE rockers. But hard to imagine such damage in just 1 hour caused by hardness anomalies so need to investigate oiling further... maybe crank engine without valve covers and check how much of a mess I get.
Meanwhile I need to start sourcing new parts. Cams from another vendor to eliminate that question, and rockers from I don't know where. I would be happy with any advice on rockers... can not take any risk of a 3rd disaster

My guess is rockers are at fault. Compatible materials and properly ground faces are critical.
