Probably more important than the manufacturer of the cam bearing is the correct set up of the gear drive lash. I would not mess with S&S choice of bearings based on the sole ground that I am familiar with other brand names. Selecting the right bearing is a science and I always left it to the pros.
Moreover, S&S provides the Torrington B 148 as inner cam bearings, why would they settle on something below this standard for the outside bearings.
