Cuda Dilemma

Don't you always use new lifters and cam, and do the usual breakin?
You know, I see alot of people on here saying they wiped out their new cam.
Back in my younger days I would just get what ever used ,new , parts I could get my hands on for street racing and never have an issue. I also have built a whole lot of new engines and never gone through the cam break in procedure. I myself have never wiped out a cam. Just dumb luck I guess.
