Hello, I'm hoping for some quick input on a possible purchase. I'm looking at a mint 96 cobra in seemingly mint condition for cheap. The owner "thinks" it has a bad head gasket because it overheats and blows exhaust smoke. I'm awaiting responses from the seller so I don't have any exact details yet such as compression tests, milky oil etc. However, I've heard that cobras of this era have bad cooling and have been reading of similar problems but the culprit being simpler cooling issues compared to a head gasket. I'm probably being hopeful but if anyone can chime in I'd greatly appreciate even if anyone knows what cost to expect if it's in fact a head gasket. Thank you
