400 bucks. What? To replace one. I doubt very much valve guide replacement on a 5.3 chev V-8 is no less than a 1000. Unless a person just brings them the heads and removes and replaces them on his own.
There isn't a single reputable auto repair shop in my city that charges less than 125 an hour. I'm not familiar with the op's location nor how busy the repair shops are.
