That's fine. Should rise a bit as you come off idle, but shouldn't rise beyond about 14.5v.

Re: alternater charging
Original Bosch/Beru specification for this era of Bosch alternator was 13.9 - 14.2 volts. if the regulator brush pack has been changed at some point the output might be a little higher. Aftermarket units are often set at 14.5volts to better charge newer calcium/silver sealed battery types that are the normal nowadays and have pretty much replaced the older lead/acid that these vans originally had fitted.

I thought the preferred charge voltages were 14.4v for the older batteries and 14.8v for the newer chemistries?
