Not true (bold and underlined). It would be either of the 2. A small base circle cam can be used with standard roller lifters, dog bones, and spider and are concidered reto fit cams. The other way would be with a standard base circle cam and link bar lifters (prefered route).

Gator, it does not have to be solid roller on the link bars, you could use hydraulic link bars as well and make sure the lifter bands stay in the lifter bores. You have to do this with solids too.
