I have those PDFS stashed somewhere, still, Nice thread.... however, the 1ZZ is almost a totally different engine to the 2ZZ isn't it? The work Yamaha did developing the heads isn't close to the extent of the differences between the two.
I mention this because I don't expect to see that radical of a change between the FB20 and whatever engine designation rests in the FT-86/FRS... It would be nice to have such a pleasant surprise though, not to mention the 40% power boost between the two variants
