Pics is not very visable, any used housing with more than 15k miles is going to show a small wear groove on the side where the small piece of the apex seal rides. Flaking in the power stroke(exhaust stroke) isnt a very big deal and you may have a bit of blow by but it wont affect compression and you will likely never know it is there. It is really hard to see with the pic you posted though.
