Kohler K482 questions - 0il leaking from head

[BMW1 42]

I have a 1973 18 Automatic.  While cleaning up the engine shroud, on the right side, sitting on the tractor, I noticed wet oil on the bottom of the cylinder head.

 

Once I wipe the oil off, it stays dry until I run the engine for 5-10 minutes then it will be wet again and the next morning there will be a couple of drips of oil on the floor.

 

I'm still new to this hobby and am thinking I need a new head gasket. I have not removed the head yet.

 

I also noticed a tag on the engine shroud, see picture below.

 

Has anyone else had this oil leak problem?

 

If I order a new head gasket, do I look for a K482 or K532?

 

Would it be a good idea to replace the gasket on the other head, even if it's not leaking?

 

Thank You.

Check around the valve cover gasket above that head - it may be leaking and getting blown down around the head/fins . Also , get up underneath and look for any signs of oil coming from the hydraulic pump - the engine flywheel fan can suck the oil into the engine's cooling fins when running . You basically have a K532 if the engine was rebuilt with that short block - the other external parts don't matter .
