Question on Comp Cam Rockers 1622-16

All,
Regretfully, all the news is bad. 2 lifters we're bad because the two cam lobes driving them wiped and rubbed thru the lifter bottoms. Have yet to find any shavings/pull the oil pan/cut open the oil filter. Engine is being pulled during the next few days. Out of frustration, I have decided to simply avoid this issue on the rebuild and shift to a roller cam and lifters(while taking another BIG bite out of my $savings). Ordered new parts today but they were darn pretty scarce due to COVID-19 logistics/manufacturing impacts across the industry. Had to have a custom cam machined since we could literally not find ANY in stock (various sources) that were similar grind to what I was using.
Spoke with Dale Meers (Dyno Shop owner/operator) and he was surprised but not shocked. He is a distributor for Comp Cams (which is what I had) and he has seen more & more poor quality (meaning incorrect metallurgy, soft, etc..) cams in recent years than in the past. His shop dynos/breaks in hundreds of engines a year and they use the same proven preps & procedures for all of them with VERY RARE failures. (I guess I was just lucky). My dyno runs on this engine went smooth with good Oil Press & temps and no detectable metal shavings/bits in either the oil we drained, the oil pan, or in the oil filter we cut open. The lobes must have wiped during the ~10-minutes of running I did just after install and driving 2-3 miles from the shop to my house(using brad penn Hi-Zinc 10-30 oil). He offered to help me negotiate some type of $$ financial restitution directly from Comp Cams if I want to pursue it with them.
I'll be crying in my beer/upset over this for a few weeks at least. -Scott
