is it worth the effort? (cam)

on the roller rockers you must do the mid lift procedure to get the correct length pushrods so the adjusters are with the ball just below the rocker
do not do any rpm with the adjusters screwed way down and too short pushrods
you want a narrow witness stripe on the valve stem when marked with Dykem or a marker
it does not matter much if on center or not- that's not the goal- narrow is but obviously too far to one side of the other means you have the pushrod length wrong or the the rocker arms to long or short
there is a list of rocker arm lengths somewhere
