I'm working on a similar build, with ZZR250, the same engine as the old Ninja 250. I have picked up my reworked block today with 2.5mm walls & 66mm bore, i used ZZR600 liners, bored out from 64mm. Will use ZX6R 66mm pistons & 2 base gaskets to avoid to high a compression ratio ! Everything else will be standard for now, but I have a few tricks I developed on previous builds that should boost power  More when its built.
Does anyone know if the Cometic 66mm head gasket will fit the old engine ? They only list a 64mm bore for the old engine !

Here's the liner out of the block. Note that there are 4 steps in the liner measuring 70mm at the top then 69.3mm then 68.5mm then 68mm at the skirt. 1mm is plenty thick where the piston is at its slowest speed.
The old and new head gaskets are different and not interchangeable.
I also included a picture of the orings in the block, one is also visible at the top of the liner.
