you want the 84 mm pistons, just heat up the block first and hammer them in there

No. If your bore is actually 81.5mm you need 81.5 pistons not 81.25mm pistons. Take it to someone with a inside micrometer.

the info is right:

.020" or .5mm is the piston size the block was bored for.

therefore, you need .020 or .5mm pistons...easy as that. Just call me if you have any questions.
