Yes,I even juggled the rockerarm geometry on way or another,but it only made a difference in lift of a few thousands.Generally, the rocker should be over center the samw amount when the valve is closed and when fully opened and the rocker tip should contact the middle of the valve stem as much as possible.
This is something to keep in mind when camming an engine,you aren't getting what you think you're getting.
Be best to check the lift at the lifter,then at the valve with the stock cam or any cam for that matter to see what the actual ratio is before ordering a new cam.Not only is the lift affected,but also the duration.
