Just a gasket? Why not replace head gaskets?

Will do diagnosis tommorrow in my garage, if its an easy fix will just do top end--but if it involves a piston too then trying to see if anyone has a recommendation on a long block company to try to get back in the water. 115 degrees on my dock today on Lake Hartwell GA, about 80 miles northeast of Atlanta.

No kidding - that's not fun - usually it's over heat first then head gasket.
