valve chatter 360 magnum

So many questions,

1. Is it a hydraulic roller cam?
2. Does it have adjustable rockers?
3. Do you know what the preload is?
4. Do you know what the bearing clearance is?
5. Have you tried any adjustments to get the noise to stop/quiet down?
6. Does it have stock magnum roller lifters in it?

Before I did anything at all I’d figure out where the preload is now on the lifter and try a few different adjustments to see if it makes any difference. That would be my step 1.
