blown head gasket or?

Hi guys, I have a 52" exmark lazer z hp with the kohler command cv23s in it. Motor has 939 hours on it and I have noticed that sometimes when cutting it loses some power and is starting to smoke on start up and at low idle. I also seen a couple small oil spots on the garage floor. Also at low idle it sounds like it has a miss, I checked the compression and one side was Just over 180 other side was a little more. Any info would be greatly apreatiated.
