It could be that the instructions are for a different engine and that the lifter would drop too low in the lifter bore on certain smaller base circle cams?

Here's the confusing part for me. The other member removed material (0.035") from the beveled edge (top portion of dog bone) to create the added clearance to allow the lifter not to move the dog bone during operation. But the lifter will travel up the lifter-bore the same even on low lift cams so why is added clearance needed?

We have a lot of wiggle room for the bottoms of the lifters on a small base circle cam so it might be a non-issue but if the highest point of a lifter only travels so high in the lifter bore despite cam lift choices, why is clearance being added so the dog bones do not move on certain cams? Would this not support comp cams instructions?

Again I apologize if I am coming across stupid but unless I can make sense of something I am unable to process information.
