Whats the history of the engine? Has it been running long?
If this is a old engine just started after a long time, give it a while to see if they improve.
If it runs OK, I would drive it as is till you were really ready for a tear down. If you have no knock or rough sounds, it sure won't hurt it to drive with low compression, it will just be down on power a slight bit. A valve adjustment might help a little.
