I have a copy of Nottinghamshire Hearth Tax 1664 : 1674, which includes transcriptions of most of the known Notts Hearth Tax returns for those years. It covers the whole county, and most parishes are included at least to some extent.
If you have traced any ancestors back to that period, I am more than happy to lookup their name (there is a surname index). Or if you are interested in a whole parish, it would not be difficult to supply the details of a parish.
Generally most entries include the names of the householder, and the number of hearths they were charged for (or in the case of poor people, the number not charged for).
Please send me a PM if you want a lookup (or post on the Notts lookups board).
