Well, if you are re-grinding 25 yr old lifters, yes you DO know what you have. And that is: quality, US made lifters, that will not fail if they are properly re-faced & broken in using the correct procedures.

If you buy new lifters, doesn't matter what cam company, because none of them make their own lifters, you do not know what you are getting....
