Lunati Cam Noise

I've got the 704 Lunati cam in the 340 in my Duster with Crane ductile iron adjustable rockers, 1.5 ratio. That puts the lift as advertised at .513/.533. It's definitely not the quietest running valve train I've heard, although I wouldn't say it's crazy noisy either. I've adjusted the valves a few times, doesn't seem to make a big difference as long as I'm in the typical range. It's not as loud as a solid lifter set up, but I definitely adjusted the valves a couple times shortly after break-in "just to make sure" I had them right because of the amount of noise it was making. I run aluminum valve covers too and I think that amplifies the sound a bit.

The lunati's have a pretty fast ramp, I think that makes for a bit more noise than a slower ramp cam just because of how fast everything is opening and closing. I also think how much noise they make is pretty subjective, what I think is noisy someone else might think is quiet and somebody else might think is normal.

Does the Mobil 1 oil have enough zinc? I use Brad Penn 10-40 in mine, runs about 60 psi for pressure when warm but I've got a high volume pump.
