Comp Cams...trouble in paradise?

Bottom line, modern engines got better, so motor oil didn't have to.

Use an oil that has at least 1200PPM of Zinc in it.
Follow the cam makers recommended break-in proceadure, yes that means you may have to remove the inner valve springs on some cams.

Do this & there shouldn't be any problems.
I have never lost a camshaft by following this guide.
