I know, trial and error, someone must know the effects of valve spring pressure to adjustable rods, there is that theory of shorter rods and more oil in lifters, but does that cause slack at certain rpms or crank them down to practical a solid lifter/tolerance...??.. Too many factors.
AND !!!!!! I'm still getting 30# oil pressure at a hot idle !!! GO figure....

There was a service bulletin issued years ago to "inspect and/or replace" lifters at 25,000 miles.
EV-27's have aggressive ramps.
Load the lifters to .140".
S&S lifters
50W in ambient temps between 60-80 degrees to help maintain proper lifter "hydrology".

That's what I've been trying to indicate to others. They put in bigger cams and some with head work and new springs and don't realize how much more pressure they're putting on the lifter and that is why they are getting more clatter at higher preloads because they're lifter just cant handle it. Less oil cushion in the lifter....

When you got to a more advanced camshaft, ramps lift etc. I really Don't think a standard lifter is gonna suffice. There's a reason S&S cost more.....
You know, don't expect a caddy when you bought a valiant.....
