Are they glazed ?

I would recommend you take the whole lot to a friendly engine conditioners - you should fit new rings anyway, so ask them how much they will charge to measure the bores, pistons and, if it's all within acceptable tolerances they can give the bores a light hone. It wont cost much and will give a fresh finish for the rings to bed into.

 

You can just buy a de-glazing tool but they do leave a smoother finish than a real hone. The coarser honed finish helps hold the oil for the piston.

 

The tool will probably cost about the same as a hone by a pro.
