I go back to the days when the INA issue first surfaced. No Wizard....that was not 1903...it was the early 90's as I recall in the EVO.
Anyway, folks started having cam bearings fall apart and naturally the buying public started to ask questions and discovered the MOCO switch to the INA was the issue. Harley defended it at the time by stating the INA bearing worked in absolute harmony with any MOCO cam, but aftermarket cams were determined to have a higher lead content, which was causing the problems. So, we all learned to pull the INA and replace it with the Torrington if/when we went to aftermarket cams.
I don't know what Harley thinks about it now, but the general rule-of-thumb is to pull the INA bearings anytime you get close and in particularly if you go to an aftermarket cam. I understand that the INA allows for a little "sloppier" alignment, since it has fewer rollers. Harley would never say it let them slip tolerances....they just said everybody else's cams were full of lead.
If my wife, or any of my pets had INA bearings.....I would have them pulled in favor of the Torrington...which is now part of Timken.

"If you are hesitating because you don't have the puller, Advance Auto rents them and you can install the new ones with the old cams."
I knew about renting a puller, but could you explain a bit more about installing the new bearings with the old cams? Do you use the old cam to tap the bearings in? I would really like to avoid buying an expensive tool I will only use once.... Thanks for the info.

BTW, how do you know you will only use it once??
