Anyone use Lunati mechanical flat 30200740?

If trying to crutch the dynamic compression a bit I would prefer to have a cam on a 108 lobe separation installed straight up (108/108) than a 110 installed four degrees advanced on a 106,just my experience.
The Comp cam in it now is installed at 104
Advanced 2* (from 106 suggested. )
Cranking compression is 175 average
I know that probably has a lot to do with pinging on 91 and only able to put 30* total timing.
I could try retarding it at 108*
Just not real crazy about that cam.
That's why if I'm in that deep might as well replace it.
It's a driver I know the converter is tighter then most would run.
Maybe Solid flat is not the way to go.
I've had a few bad sets of hydraulic lifters within the last couple years is why I was thinking of going Solid.
The main reason for wanting to change cams is the noise. (Comp. XE.)
I've had mechanical cams that were quieter..
