1988 Toyota 4Runner not sure about my head gasket?

Engine Mechanical problem
1988 Toyota 4Runner 4 cyl Four Wheel Drive Manual 280.00 miles

my 1988 4runner has some oil in the coolant I think I'm not sure but that's what it feels like but it could be stop leak. There is no water in the oil it doesn't miss and it only smokes a very little bit for for maybe one second when I first start it someone told me that my head gasket was blown but other people have told me it wasn't. Im just trying to figure out on my own without paying to much and/or doing to much work.
