Just for info, we got our KB block in 2009. We've ran it since then with no lifter oiling and no bushing. Always used solid roller cams and we have had no issues X2  Same here. Been running my KB block since 2006 w/ no lifter oiling and no problems at all. Street and strip w/ a solid roller cam. No prelube either.
