He is killing parts so it's already sideways. He needs a different mechanic if he's checking pushrod length without soft springs on it.
IMO, 2 threads out of the rocker is too much, especially with the W-2 and the offset intake rocker. It should be 9/32 inch plus or minus .025 which usually equates to no threads out.
Putting the adjuster farther out also changes the rocker ratio. Not by much, but a bit anyways.
