That's a 5 chain engine. I'll bet your deviations have an underlying condition impacting them... You just aggravated it enough with the IMSR to wake them up.

This is why we check deviations before a process as part of the pre-qual and if the values are out of my spec, the engine doesn't get touched. If it is we end up where you are if they reach the CEL triggering point.

These wear horribly, even at lower mileage. I will bet you this is impacting the values and you probably didn't do anything wrong. You just "finger Fu***ed" it by touching it. The CEL would have set anyway.

Moral of the story? Assume nothing and quantify everything, including cam deviations before the process is done.
