as you well know, cylinder bores are matched to the pistons.
... just meaning to say it's a close match with a specific clearance tolerance.

So when a good shop hones your cylinders, they'll likely want to have the applicable pistons at hand so they can get the size and piston-cylinder clearace within the allowed tolerance.

those 81.965 pistons will be too small.
