Vaccum's level depend on how radical or stock your cam may be (the higher the reading the more stock it is). Stability is what you want. If the needle wanders it means trouble in the valve/valve train area (so you are OK and probably have a stock engine cam). It could also be a sign of a really weak cylinder I guess but this may not be the most accurate way to check it.

I'm not too confident with only vacuum reading results.My dads motorhome with a 454 Chebbie was blowing smoke out of the one side of his dual exhaust so I did a reading on it.It was around 25 inches and as steady as a rock.Did a compression check and he had two cylinders on the same bank with 0 compression.When we tore it down the rings and ring lands from the pistons were laying in the oil pan.
