Absolutely not if they came out of the cylinders you picced as rusted. No way will those rings be good, you are not looking nearly close enough. And, used rings on a non-matched used bore screams oil burning issues.

You CAN sometimes re-use rings BUT only under certain VERY tightly controlled circumstances. Anything else will be a f-ckup. Switching cylinder blocks in there will not be one of them and death. I'd bet any money on at least one of those pistons being bad as well.

Ok thanks for the input I plan on using the Pistons that are coming with my replacement head. I guess I will order new rings as well.
