Cup Style Pushrod Adjuster Screws

As yet to determine the pushrod length I will need, waiting on the arrival of the B3Racing correction kit for that. I’m still sussing out if I should swap the ball adjusters to cup style for further better geometry (and use oiling pushrods) This is a question for those that have actually changed from ball to cups: What, if any, change in valve lift was realized? In your case, or of those you perhaps have setup. I understand it will vary in each case. Mike at B3 already mentioned that the Erson roller rockers (shaft to tip centers) I’m using are slightly short on the valve side, and in my situation the shafts will only be going up (not away, and not worth the work to modify the shafts to move a little closer to the valves) I failed to ask him about the ball vs cup adjusters. Wondering if any additional lift (however slight etc) could be gained on the pushrod side? Weekend wonderings:)
