I don't see this as being any different than points-type ignitions. Kettering invented the system early in the last century and it endured for some 70 years. When it came time to clean up the environment, the OEM's switched to electronic ignition and we never looked back. Now we have moved to solid state ignition with a coil for each cylinder, controlled by computers. Same with carburetors. Electronic fuel injection is light years ahead of the old technology, contributes to vastly improved fuel mileage and much cleaner emissions.

The only cure-all that I see is a change to roller cams. With them, there is no special procedure for break-in. You just oil them, drop them in and drive. No hocus-pocus or special lubricants. Be advised though, that there could be a problem with mechanical roller camshafts in a street motor. The best application for a street motor would be a hydraulic roller cam. Most of them will have a rev limit of around 6,000 to 6,200 rpm's due to the agressive lobe design, but if you need more r's than that, you're not building a street motor anyway and should consider a mechanical roller cam. The old flat tappet technology is just about dead, save for a few of us old die-hards.

For those of you who insist on using flat tappet cams (more than likely due to the cost of roller units, particularly if building a pre-roller cam type of block), I will herein give my take on the best way to do it.
