Re using cast iron rings?

I would not hone....no need to, ring is already seated

I would not re hone if the original cross hatch in the bore was still present.
But that is not likely to be the case.
If the cross hatch is gone and the bore is smooth, the ring is not 'seated' nor is it sealing well.
The cross hatch is present along with the plateau hone to retain oil on the bore side walls to lubricate the piston rings.
