Cam Issue

Was told by a mopar racer that many people do not brack in their cams properly, in that they do not use the break in lube. It was mentioned to me that I use a bottle of G.M. ( thats right)"engine oil suppliment" when I crank up my nwew 340 for the first time.
The fed government mandated the removal of all lead from engine oils a few years ago and that ,that has contributed to the faileur of cams of all brands, if steps a'rent taken to remeddy the problem. Oil Mfgs havent added any other additives to counrter act this problem, to thier oils.I was told by tis person too use the G.M. addittive for this very same reason.
I called this source up to day cause I am concerned about my new engine, after reading these thredes And that is what he told Me. it is not the cams but the way tey are broke in. I have the M.P cam #p4452761 installed in my engine and am about too fire it up.
I am still worried

I'll let yuo all know how it goes.
if any one wants the name of my source you can P.M. me and I'll answer as ap.be patient I work 3rd shift.
