PISTONS Drag Specialities
I bought these Drag Specialties + 0.10 pistons, I can't find any arrows (which usually indicate the exhaust) on the face and the valve seats are the same size.
The only marks I find are those highlighted in the photos.
Who knows them and knows the correct assembly?

I didn't understand correctly The cut out goes towards the connecting rod JCC type pistons
I measured from the piston pin bore, front and back and the measurement is the same. The hole is centered
I measured the valve faces on the piston head, and they are the same.
I've mounted the pistons in the cylinders in both directions and the top dead center always stays the same and the pistons don't wobble.
In the absence of arrows and other signs can I say that the pistons do not have a forced direc????
I wrote to JCC in Taiwan for instructions but got no response
The only doubt is this step.

I take it that there is only one cut like this on each piston ? I looked up piston wrist pin offset and found this. Do you have an original piston to compare to.I think you are doing to right thing by looking into this. I would be afraid to use those pistons until I knew.

See above about what I saw about offset. I was doing an edit while you responded. Looks like to me that those pistons do not have it. I myself do not see that step.
