I agree with you that is most likely the assignable root cause of my cam/lifter excessive wear.
I definitely searched out and found a very reputable engine builder to go through my heads and setup the valve spring pressure for my roller cam.
I wonder how many cam / lifter failure were the results of weak / improper setup springs ? Usually the blame goes to the wrong oil and break in process.
My springs did not have many miles, but I understand the concept of fatigue and thermal cycle impact.
