Should have a trusted shop look at this, it is possible the heads may have warped causing a bad head gasket. But always check the least expensive part so ya, I would try the thermostat first. Also a compression test would indicate if a head gasket is blown. And it could be as simple as purging the cooling system from air.

Check to see if your water pump is really pushing water. It might not leak but it may not be circulating your coolant.

also...if you have a doubt in your mind about a block thermostat that is less than 5 bucks why not change out cheapest parts first?
