But yeah, if they are custom pistons, you'll be SOL if they don't fit (no exchanging).
yeah, 5k and 58k are a bit different.
If you were able to achieve those tolerances on each piston that's awesome. Was your block an all A or all B block? all my blocks except one have been ABAB blocks. Did they do it by a data sheet or did they actually measure each piston?
