This thread scares the hell out of me too. I am running the lunati rollers in my engine on a voodoo cam that GTOFREEK spec’d for me.

I have the same lifters running on a comp roller. While mine are a bit noisy and sometimes inconsistent, I've not had a single reliability issue with them in over 10,000 miles.

When I talked to lunati about the noise, their response was that they coat the product in a rust inhibitor and that due to EPA mandate, that inhibitor is water based.

So when it mixes with oil you can get a sludge buildup that can hamper functioning of the lifter.

His recommendation was to run some sea foam through the engine oil right before an oil change, then re-adjust the valves and first carefully bottom out the plunger to push and of that sludge out of lifter body, then set pre-load followed by an oil change.

Their installation instructions say nothing about cleaning, but it's pretty obvious here that these things need to be cleaned well before they are put into service.

If you haven't put them in the engine yet, I'd take them apart and clean them thoroughly in solvent before installation.

If you've already installed them, try the fix above. I've not done that yet on my engine, so I don't know if it works of not. Considering others here and in other threads have mentioned the same issue, I feel it holds some weight.
