Do 1.015L (not 1015cc) barrels fit z900 bottom?.
Cam chain tensioner looks same fitting but not sure about height of barrels.
Crancase has already been enlarged for large liners when fitted RC 1170 pistons with bigger liners many years ago but were knicked.

Yes!
The 900 and 1000 cases are pretty much identical apart from the case mouths which you have enlarged already.
Deck heights and even the heads are basically the same..
The 1000 is just a bored out 900.

Many thanks zed1015 thats really great news!!
