Car 1: Honda Legend KA7

Could someone measure the piston protrusion, please? After machining the engine block, I have the following data:

Measured like shown in the picture, the small milled plateau A in the middle of the piston has been measured refering to the cylinder wall. All pistons are lower than the cylinders:
Cyl. 1: -0.2mm
Cyl. 2: -0.08mm
Cyl. 3: -0.2mm
Cyl. 4: -0.1mm
Cyl. 5: -0.13mm
Cyl. 6: -0.17mm

Measuring the piston at positions B, I got the following data:

Cyl. 1: +0.02mm/+0.04mm
Cyl. 2: +0.06mm/+0.04mm
Cyl. 3: +0.03mm/+0.05mm
Cyl. 4: +0.1mm/+0.13mm
Cyl. 5: +0.08mm/+0.10mm
Cyl. 6: +0.07mm/+0.04mm
