Log entries other than the VOR aircraft log record are not part of the ramp check check list or inspection requirements listed in 8900.1. I would not permit entry into the aircraft during a ramp inspection, nor would I immediately produce any maintenance entries at that point in time to preserve my rights. Remember that anything you say may be used against you.
The VOR aircraft log check by the pilot is not considered preventive maintenance and 91.171 d) states: Each person making the VOR operational check, as specified in paragraph (b) or (c) of this section, shall enter the date, place, bearing error, and sign the aircraft log or other record. I keep a separate VOR check log. This is one of the items that if kept in the aircraft, you are required to produce during a ramp check.
Even though I routinely check the VORs and make the aircraft log required, I haven't actually used them in IFR for the last four years, since my GNS530W was updated to software version 3.0 and was certified for sole means of IFR navigation. I only do this because there is always the possibility that WAAS may be unavailable and I would need them for navigation. WAAS being unavailable is extremely rare, although there was a complete outage that lasted 4 hours back on Oct 21. WAAS being unavailable is different from not being able to obtain vertical guidance on approaches.
