These are 2.0L (94mm) cylinders and have about 1 to 2mm dish.
I thought that the low compression pistons had about 5 mm dish.
Anyone has any idea what CR are these?

They look like deep dish bus pistons (could be just the pic), but if they are indeed a "1-2mm dish" then they should be stock US spec 914 pistons.
IIRC they are around 8:1cr.
They look odd because they are too clean...What markings are on the top or pull one and post the markings cast into the bottom of the pistons.

ARCO gas?
bus pistons have an obvious step down

Bus pistons look like an ashtray. Unmistakeable.
