Is the Chinese gauge the only thing that indicates to you that you are over heating? Wow, I see absolutely no oil leaks! By how much? Some recommend a candy thermometer to measure oil temp down the dispstick tube --- or a known accurate oild temp gauge. I would do search and make the quick and easy hood prop to keep engine lid open a couple inches when in traffic.
Looks like all the cooling tine is there - can't see the dog house cooler though. Looks like aftermarket shroud - the OEM on has internal vanes and directs air flow better. Does it have the thermostat and flappers (for quick warmup)? I've seen others block off air to the heat exchanges (with plugs at shroud outlets) in the summer when heat isn't used. The way heat exchangers work when hot air not going to intereior is to dump it at the front of the engine (where it ofter get ingested again -especially when sitting in traffic with no air flow under car). Looks like exhaust leaks (carbon black tracks) where heat exchangers attach to exhaust on each side). A ceramic coated muffler will expell heat better than non treated one.
