Zinc Rich Oil for Flat Tappet Cams

Ok everyone! I know this has been beat to a pulp. But currently what oil preferably conventional is good enough to run in a 360 with stock clearances? I have been using 30 weight vr-1. But need other sources of oil please!!:)
Why switch from vr-1, it contains the zinc needed . I've been using Valvoline racing oil since the 70's.
Not one cam failure or bearing failure, not one! If you're gonna gamble, why not switch to Tech 2000 and a can of STP?
It is your dime, not mine.
