Rocker Arm help

Care you elaborate more on “cutting the heads”? Where does he say the shaft needs to go? I know Mike has plenty of experience with those heads and the different rocker combos. I assume you took the measurements he needs to determine that. Revealing that would put the kibosh to the back and forth of it needing to go up or down etc.
He said the shaft needs to up and towards the intake manifold. Mike has already posted here so I doubt this will put the kibosh on anything. The cutting the heads I was referring to was related to some of the speedmaster heads having saddles that are too wide and allow the shaft to move. This was discussed in comment #11-#20
