Darton sleeves
A used block has been stress relieved in service so no further stress relief is required.
I recommend any new block to be stress relieved whether being sleeved or not. Then hone the cylinders round with a torque plate attached, check the main bearing bores at the same time and align hone if necessary. Stress relieving a new casting will give you a much straighter, rounder cylindered block in service.
