antifreeze in exhaust

[Yamaharider74]

hello removed the head off of my 06 apex and i noticed there is antifreeze in the exhaust ports it almost looks like its running down the one valve guide rusty color
I don t know the history of the sled any tips would help thanks

Possibly a head gasket. There is no coolant above the valves that would allow coolant to run down the valve. I would think it would be getting into the combustion area and then its being pushed out the exhaust valve port. What color is the oil? Does it look milky?

Thanks at least now I know there is nothing that can come out around valve stem
