If you run a 180 through it, I would put new rings in it. That's pretty rough, and will be like breaking in again, look at the second ring face with another break in the taper will probably be gone. Then you will get into a loss of oil control.

It really depends on what you want to do here. It really needs to be bored, honed to be put back to perfect. But if the intent is not to do that, 500 the bores and put it all back together. Anything in between that would just be a waste of time/money in my opinion.

One more thing, 500 will need considerable pressure, if using an expandable hone.
