Question on Comp Cam Rockers 1622-16

Guys, Appreciate the feedback. Will know more this time tomorrow but here are additional details:

1) Engine build was completed in early Jan2021
2) Engine was broken in and dyno tested at Dale Meers facility in Buffalo, Ky in late Jan2021. This included a lengthy pre-lube and verification of oil flow at rockers; ~20mins run @ 1800rpm and another ~20mins at ~2200rpm. After a cool down, engine was restarted, carb adjustments made and several dyno pulls made. Oil Pressure & temps were good throughout. Upon completion, oil was drained and inspected and oil filter cut open. Looked very clean except for a small number of VERY fine shiny particles that might cover a pencil eraser or the tip of your pinky. Refilled the engine with normal, green, high-zinc brad penn oil and new filter.
3) Dale gave the engine a good bill of health and said, "it's ready to run however you want to run it.."
4) Engine sat in my heated garage until last week when we installed it back in the car.
5) Cranked engine for about 20-30 seconds to help with pre-lube. Connected coil wire and engine fired up without problems, except for a few oil leaks, etc...No sounds of valve train noise.
6) drove the car ~4 miles to my house at 35-50 mph. Only had some temp exhaust tubing in place, so it was a little loud, but did not hear any unexpected noises.
.....which brings us to the present. If the cam is wiped, I can't imagine what else could be done to ensure it wouldn't happen again....
