Looks kinda norm to me. Some could have to do with the type of gas being run, but that looks to me like it is working exactly the way it should be.. Lets not forget that exhaust valves get a good bit hoter then intake valves, are made of diff material alot of times.. So the colors they change will be diff.. Clean them up and roll with it..
