89 360 vs 71 360

While waiting at doctors office I started reading in Hotrod about Jesel roller lifters. I didn't get to finish the article. They were talking about Bushed roller lifters (For Street Applications) and how they don't wipe out your motor like the needle bearings do .I didn't get much further than that but maybe someone can elaborate . The may not even have them for small block mopars. Also I am talking out my butt when it comes to roller set ups as I have no real knowledge on this so don't beat me up too bad. I prefer standard solid cam lifters my self as I don't race much.
I found this. Opinions ?
