Without punctuation this is really hard to figure out what you're asking. It can be read numerous different ways. If this is a vehicle you're thinking about buying, if the needed repairs were easy or inexpensive, the seller would have done them already. People sell cars with problems because they can't solve them or it's going to be expensive. With GM vehicles, you can assume it's going to be expensive.
Your diagnosis based on you can hold your hand on the engine is one I've never heard of. You need a scanner to view live data to see exactly what the coolant temperature is. There's a chemical test for a leaking cylinder head gasket. Any other observations are just guesses.
We don't get involved with costs here because there's way too many variables, plus, we don't even know what's wrong with it.
