You can run a tool steel lifter on a cast cam with proper breakin and lubricant selection, with that being said you can run a tool steel lifter with the proper coating on multiple cams of the
right material/treatment processes with no issues. I have ran tool steel lifters from a few suppliers for over 5 years without a single failure using a few procedures and the cams have
been sold and look like new, i have reused one set of lifters on 3 cams and switched back
and forth with no issues. If things are done right you can run any oil you want, hope that makes things as clear as possible.
