1621 comp pro mag rocker arms

Just getting ready to check engine for pushrod length,I have a 493 rb stroker with 240 trickflow heads and 1621 comp pro mag steel roller tip rocker arms,,I have a question or questions,How far down do I want the cup adjuster sticking out of the rocker arm where it meets the pushrod,I read somewhere that the adjuster has an oil hole in it and it cant be set too far down toward the pushrod,I took one apart and do see the oil hole in the adjuster and there is an oil hole in the rocker as well,do these holes need to line up,if so then I cant bring the adjuster out any as the holes only line up with the adjuster all the way in on the pushrod side,hope I made my self clear,thanx in advance,its a hydraulic cam with around 563 lift

They are designed to oil with no more than 0-3 turns from bottomed. The adjusters with the kit I had seen have a band of removed threads to allow this proving the 0-3 window for adjustment.
