Hi!
Most likely, these sleeves can be used.
But with this volume may be a problem ....
I faced a lot of problems ... however, my engine is not the typical ..

I've got a 1.2mm (I think) copper base gasket. Had it made at a local engineering place.
Needs a clean up on the edges but good to go if it's the right size?

Cylinder spacers shouldn't be hard to make. Every company with a laser or water cutting machine should be able to do it. It's quite cheap, too.
I work at a company which has watercutting machine and I have even worked with it. Can be used for cutting wide range of materials, like metal, plastic, stone, wood. It wouldn't be a problem to make spacers if I had a CAD drawing and some material of the right thickness.

I will ask R&D at my work. If they can make a cad drawing in there free time, and ask if they know a good laser/watercut company nearby. I need the sleeves first so i can determine what the diameters will be. Thank mates!

and what pistons do you have?
spacer can be purchased at cometik. or cut with a laser.
