These are both 90mm (2.7 liter) KS Alusil cylinders.

90ZN2 W1
90ZN2 W2

These are most likely 90mm (2.7 liter) Mahle Alusils.
Check to see if the inner bore is slightly magnetic. If the wall do not attract a magnet (like the KS cylinders), they are Alusil.
If they attract a magnet, they are Nikasil.
