Oil is changed 2x per year, depending on the cars use; clean oil is supposed to be the mail thing to stay on top of with a bushed lifter. I have another near new set of the Isky Red Zones with needle rollers with little dyno use only - I might send them to Isky for conversion, I wonder if there is a contact for this, hmmm.

So far, so good up

I asked them about converting mine from needle bearings to bushings a couple years ago and they said no problem. Costs around $700 IIRC.
