I listened to my solids for a long time. Fiddled with settings, different push rods, etc., and just recently put a new cam in and went back to hydraulic units since I don't ride as aggressively as I used to. I thought something was wrong when I started it up, it was so quiet. I have decided that I like it. I just hope these new "Sifton" lifters hold up. They are not made by the same folks anymore. Didn't realise this at the time but so far so good. They have made it for about 2k miles anyway.
Sometimes, the problem is, there is no problem. We get to tinkering, adjusting, tightening, and create or conjure up a problem. As in the case of pushrod and solid lifters for shovels, they are somewhat noisy, aluminum or steel. That's just the way they are. 99% of people never ever run their shovels in the rpm range that would cause them to consider light alloy pushrods to speed up the valve train (4500-7000 rpm).
Adjust the cold lash and leave it alone. Go for a ride.

also the lighter valvetrain components cause less wear on every thing valvetrain related. not just for speed, fastness of valve opening or more power, but it causes less wear and stress on all entire valvetrain. including rollers and friction points. the early sporty motor never had hydraulics from the get go.
