Anyone using SB Lunati cam ending in 703 Part number?

I was laying in bed thinking that I could not be a tooth off as I did degree the cam and numbers came out perfect with the info on the card. And yes 106 is correct. What is your method for finding zero lash? I would think that the whole procedure is not that precise as there is certainly some deviance in the zero lash starting point. I just turn the push rod until I feel like the rocker is making good contact and the slop is gone. Then i was using 3/4 turn as everything is new so there will be some seating in of things. Also I will be taking it all apart again after break in to install the second valve spring so I could set everything to 1/2 turn then after things settle in. Thoughts?
