Default adjusting valves with crane roller rockers

Hi, I am in the process of adjusting my valves on my 402 with ls7 lifters, I have crane came aluminum full roller adjustable rocker kit 1.7 ratio. in the instruction they tell you to adjust at 2 full turn after 0 lash. I have a dial on the end of my rocker over the push rod end. 2 full turns give me .120 preload. did research on here and most suggest around .080. that is were I had them (.080) for the last 4 years with my 1.8 rockers. any opinion on preload and why they would recommend 2 turns?

that is my plan is to set at .080. was curious why they wanted .120, seems excessive. asking because I know here there is a lot of people with real life experience and value there opinion
