Over the Counter Zinc Additive

Here recently I changed the heads, intake and cam on my 360. Was going with a Hughes flat tappet cam but decided to go with a roller cam from Hughes. I called them and changed my order. I told them to take the Joe Gibbs high zinc oil off since I will not be needing it with the roller cam. Got a call back to my voice mail a little later that I would need to run the Joe Gibbs oil regardless of roller or FT cam. Called them back and he said one of the techs HIGHLY recommended I run high zinc oil with a roller cam! I told the sales guy to leave the oil on my order then and plan on running it.

What you guys think?
I guess it's much better to be safe than sorry. I don't mind paying a little extra for protection that I don't need but just wondering.
You guys running flat tappet cams are talking about which oil or additive is the best for your cams.... and I'm sitting here with a roller cam and still got to run high zinc!!!!:mad:
