I don’t see any way those parts had 1.875” IH before.......... not without some cups/shims.

The locks appear to be sitting normally in the retainers.

If that’s how the springs are really set up, then there’s probably no need to do anything extreme when you set them up this time around.
At 1.950 the springs would only be about 105 on the seat, and a mile from coil bind.

Reduce the IH by .100 and it’ll probably be fine.
