I do have pre-gen block I can open up for you. Will have to be after this weekend when I'm back from holiday.
I’m Only interested in the new-gen block at the moment. I have one that I bored to 64mm for a 315cc. These are being fitted to 300 engines !

That upper O-ring groove reduces the liner thickness, so I’ll get them pressed out of another block & replace with 600 liners.

Thanks
