If the block and head is fine, all you need is a new piston ring. However that'll turn into a rebuild on half of the motor atleast.
If the block is damaged, it may be beyond repair depending on what happened. Scorring is the major one here, and that can be resurfaced, or bored out somewhat.
As mentioned above, the valves could not be sealing right as well. Replacing the head would be cheaper then machine work as well.
Do the wet dry test like mentioned, that'll help a lot.
