Some get lucky, but lifter failure in performance motors is not an internet scare tactic to sell parts. I had SE lifters take out a great running motor, granted it had .625 lift cams, but I know guys with more radical cams and S&S lifters having no problems. There are many documented failures of SE, Harley "C", and Gaterman lifters. The best lifters HD had were the "B" model. Agree with Ironmark, keeping cam lift near stock gives a better chance of no problems. I had 90,000 miles on stock lifters, but that was on a 80" Evo, stock cams (.472 lift), and production back then wasn't in Mexico or China.
