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 Tig did you all use some sort of prelude (Peters/accusump )? Didn't for many years, fitted an accusump after the car developed a habit of wheelstanding. Though we always pre-lubed the engine with a drill if it had been standing for a couple of weeks or so.
