Cam Install Question

you still need to do the mid lift procedure
depending on cam lift and valve tip height -with high lift cam figure half the lift increase between 340 cam and new cam and add to stock valve tip length- you will be real close - procedure definitely required with long valves- which allow bigger springs
"the adjusters are screwed way up in with no threads showing at all"
remember newer adjusters are longer between the last thread and the center of the ball- with these no threads are ok

"the rocker ratio actually increases as approaches peak lift" not if you have the line from the center of shaft to the pad/valve tip set with mid lift at right angles-perpendicular
max ratio is at mid lift

"walk/scrub across the valve tips from intake to exhaust side when going from 0 to peak lift" pad has a radius which mostly rolls across the valve tip
