Many of the problems are common to both breeds. You won't avoid them by mixing the two. In fact, you may run into a higher likelihood of problems, as a breeder willing to mix the two is less likely to be responsible enough to actually test their breeding animals for health problems common to either breed. "Hybrid vigor" is a myth when it comes to dogs for the most part, and only applies to recessive traits that are seen in only one of the breeds used. For instance, the pushed in face of the pug can cause respiratory issues, but crossed with a beagle, the muzzle lengthens enough to minimize those problems. Labs and goldens are similar enough in form and share most of their common health problems, so nothing will be "fixed" by mixing the two.
If you want a retriever with less chance of health issues, find a reputable breeder of one or the other, one who has a history of testing their dogs and producing healthy, long-lived animals, or choose one of the less common, healthier retriever breeds, such as the Flat Coated or Curly Coated Retriever or the Nova Scotia Duck Tolling Retriever. If you want a mutt just for the sake of having a mutt, go down to the shelter and pick a likelable one out of the pens. They have plenty to choose from and are overrun with puppies, especially in the spring.
