Well, I did a fuel pressure test, and here's what I got (in bars):

5.4 Basic pressure
1.9 cold engine, connector to heater of WUR off
4.1 Warm engine, heater on
3.5 with valve off ,engine running
Took 2 minutes to drop to 3.2
Took 5 minutes to drop to 2.8
2.8 seems to be holding for >1 hour

This car runs very well and always starts first crank. The concern here is leaks and gas in the oil. Maybe running a bit rich?

It is interesting to note, that when I connected up the gauges (car had not run in 20 hours), there were no leaks or spray, so I suppose that there was virtually no pressure. There were no leaks or spray when I disconnected the fuel lines over the LH valve cover when I replaced the timing chain stuff, either.

Should these pressures hold indefinitely? That's a lot to ask on an 24 year old car!

The WUR numbers seem a little high, and could be attributable to dirty screens, etc. The manual says that:
5.2-5.8 Basic
3.4-3.8 warm.

In a previous post, Chuck Taylor mentioned that 380's liked 1.0 cold and 3.4 may be better.
