The head will need to be inspected at a machine shop. They can tell you if it is warped or cracked.
You cannot tell by looking. Take it to a machine shop for examination.
Nothing good, I can tell you that. Anything from a warped head, cracked head, warped block, cracked block, and basicly, a blown engine.
The only way to tell for sure is to remove the head and look. You are going to have to remove the head in either case. Remove the head and take it to a machine shop and have it inspected for cracks and to see if it is warped.
That is the most typical thing to cause a warped head. A warped head is a severe diagnoses and not the first thing that would come to mind for a problem. Don't know what the issue is but if you have a problem that has lead to you think you have a warped head and you haven't had a extreme over heat of the motor I will bet you don't have warped head.

you have a warped/or cracked head,or blown head gasket
Bit of a tricky one ... It all depends on the condition of the cylinder head. If the cylinder head is warped then replacing the head gasket won't solve your problem. A warped cylinder head can be skimmed (if not too badly warped). If the cylinder head is badly warped then it would be much easier to replace the head than fit another engine.
