Comp Cams...trouble in paradise?

I have no hard-core info but I'm helping a young friend (40) with the 351W in his 69 Torino. The counter guy helped him pick a cam for his motor and he ended up with a Thumpr to go with the Trickflow heads, etc. The fine print on the Comp literature says the warranty is VOID if you do NOT use Comp break-in oil...period. Haven't fired the motor yet so we'll see.

I'll ask my engine guy if he knows anything specific about Comp but when I saw him over the weekend, we happened to talk about cam life and he says he has not had a single cam failure when using Brad Penn oil.
