It's not uncommon for 361/407 engines to look damp and even seep a small amount of antifreeze outward from the head gasket area when working them hard. Exhaust side and rear seem to be the worst areas.
My dad has an 806, 1206, 1256, and 1456. All are (hard) working tractors. Each one seeps enough antifreeze in at least one spot to attract dirt when doing tillage work. Scared the heck out of me when I first started doing field work. I thought I hurt his 1256 chisel plowing. 4000 hours later it still has the same head gasket. His 806 has 500 hrs. on a complete out-of-frame overhaul. They trued the block and head surfaces, and it got a quality, properly prepped, properly installed, and properly torqued (and re-checked/torqued) head gasket and it still seeps a bit when it gets a good workout.
If you can catch antifreeze in a container under the tractor as it pours out, or like Jim says, find it dribbling out of the threads on the pan plug, you have a problem. If you notice performance issues or overheating, you have a problem. If not, run 'er at 2400 rpm's, midway or less on the water temp. gauge, and 1200 degrees or less at the exhaust all day long.

The whole experience can be marred if one moves too fast and makes too many assumptions that they can just use "as is" some parts they should be closely scrutinizing and possibly attended to. In such cases, rework makes what could have been a fun project turn into an irritant or even a nightmare. Minor Irritants To give you an example of an minor but irritating proble
