This info came from a Kohler Service Manual.
The bore diameter for a 10 horse motor is 3.251.
The bore diameter for a 12 horse motor is 3.375.
The stroke for a 10 horse motor is 2.875.
The stroke for a 12 horse motor is 3.250.
The 10 horse crank will work in a 12 horse power block. I wouldn't do it....not enough stroke. The 12 horse crank will not work in a 10 horse power block. The counterweights from a 12 horse motor will hit the bore in a 10 horse block when the crank rotates.
The last Kohler motor (K321-14 horse block) I had sleeved cost around $85. That was 3 years ago. Odds are it is around a $100 now.
Is the piston new?
