I didn't order my Indy block with PR oiling. After giving it more thought, I wasn't crazy about splash oiling a roller cam so I decided to go the internal manifold route. My thought is that the lifters will live longer, especially on the street with pressure fed bores and roller axles. I could be completely wrong, but I sleep better this way.  FWIW...my KB block doesn't have lifter oil galleys and mine is a solid roller. No problems w/ lifters in 10 years.
