Attention to detail used to be enough. But now a big problem w/flat tappet cams is the influx of poor quality cam cores and lifters that make them more failure prone than they should be. Add to that the motor oil being made w/less high pressure additives that are needed when using a flat tappet cam, and the chance of improper break in procedures being followed and you have a system that fails more than it should- and more than it did, not that many years ago.

But that said, if the proper parts are used (like the correct valve springs set up w/the correct installed height), and the important areas of the valve train are checked, and the proper procedures for cam break in are followed, there's no reason a strong running engine cannot have a flat tappet cam- even a hydraulic flat tappet cam.
Agreed.
Yeah, I will be using Valvoline VR-1 as my motor oil as it has plenty of Zinc/ZDPP, and a break in additive the first time as well.
