I kind of think along the same line but then again I have heard the same story since from childhood going back to the mopeds and motor cycles.
If you ask a hard core American V8 rebuilder they tell you that you have to keep the engine at high rev for some 30 minutes right after you have replaced camshaft and lifters to harden the cam lobes and if you don't, you will wear down the camshaft in no time.
To me that just doesn't sound true but many will tell you the same story and how the camshaft was trashed because they didn't give it a run in.
I don't understand that the camshaft and lifters would not be hardened from get go and how something magically would happen during the first 30 minutes of running that would set the tune for the rest of the engines life. Like oil molecules getting trapped inside the steel only at the first run.
