'"Pre-load is a side effect of adjusting your pushrods properly" or lifter adjustment (pre-load) as you like to call it, is a side effect of pushrod adjustment.
I think you are splitting hairs... your hairs.
PS measure the height of a lifter with no pre-load and then with pre-load. Then let me know if there is a difference in height/adjustment.

Please explain how you will change the height of this lifter without removing metal. You cant.

My brand spankin' new Low Rider makes a bit more overhead noise than I am completely comfortable with, but it hasn't kicked any parts out yet.
And only solid (read: non-hydraulic) lifters can be adjusted (set variably) via adjustable push tubes.

Oh geeze, lifter/tappet are the same damn things, just different names. I'm done.
Yeah, that'll do it. "Variable" valve timing.

On a recent trip to York/Lancaster area, (800+ miles from home) we had a day of highway speed and my lifters were just a singing. Using the HD gauge in the inner fairing oil pressure probably at or near 25 psi. The next day, while traveling freeways (actually Fee turnpike) the lifters were just like normal, oil pressure at 32 psi. Just a hit or miss on noise. Doesn't seem right one has to replace with a better lifter when there's only 8500 miles on the originals.

Looks like we will both just give up! I come from the old school of panheads and shovelheads and my memories fade. A couple of pics.

To the OP:
When you say rebuilt, what exactly was done to the engine?
Did you have any machine work done on the heads?
What was the reason for the rebuild? Some sort of failure?
What parts were replaced? Cams, lifters, etc?
