Answer
Hello,

  No, don't keep running it that way.  Antifreeze in the oil is a serious problem and even a small amount can cause serious engine damage.  Even though you changed the oil, it's just going to contaminate the new oil again.  The head should be checked for warpage and cracks besides replacing the head gasket.

                Good luck,
