I got a couple sets of rebuilt heads in a recent hoard purchase and I’m currently checking out the springs. Seems every time I check springs they’re on the low side, while doing a little research I came across posts that pressure should be checked with the retainer in place? Why is that? Doesn’t seem like it’d matter. I’m sure there’s a good reason but curious to know.

I've never checked with a retainer. I guess you could if you don't include the retainer thickness when checking height. Unless the retainer has a lower step for the inner, which I've never seen, I see no reason to use a retainer. One of the 3 B's will set us straight I'm sure.

Yep, you always need to use the retainer.
The step on the retainer loads the inner spring and pushes it down further, even on an installed height position.
As stated though, you have to measure the thickness of the top "flange" of the retainer and take that into account.

Gotcha, thanks. Didn’t dawn on me as the first set I’m working with has single springs, no dampener no nothing. 197lbs @ .500” but the put new stainless valves in it and cut for positive locks, what were they thinking?!?

I have used a spacer over the inner spring to simulate the step in the retainer.
