Will a st185/st205 head fit on st165 block? What about the MR2 heads? Has it been done before? If so, is it a worthwhile upgrade?

Yes they all fit. Yes they are a worthwhile upgrade because they allow for the fitting of a greater selection of aftermarket cams. They are also a bit easier to find shimless buckets for, marginally. They are about the same though.
