I have a 383/432 stroker with Hughes retrofit hydraulic roller lifters (morel). I have had some lifter tick from day one that seems to be getting more noticeable. My push rods have holes to allow from push rod oiling, which I do not need, and I’m now wondering if i could be bleeding off some pressure at the lifters causing the tick. I have 3/4 of a turn preload and am using a high volume oils pump. Pressure is 45-50 hot at cruise and I have used different viscosities of oil with no noticeable improvement. Currently 10w 30 mobile 1 synthetic.
Thoughts?

try another 1/4 turn down, that made my Hughes [Morel] lifter a little quieter. the push rod oil has nothing to do with it.

My theory was that the extra oil travelling through the pushrods possibly was reducing the internal pressure at the lifter plunger causing the lifter to bleed down quicker.
