I don't, but I did buy a set off a 200? 496HO and put them on my 1989 454 and was very pleased with the upgrade. Gained some mid-range and top-end power plus (assuming yours are still aluminum) took a bunch of weight out of the back of my boat.
Nice economical upgrade for anyone using steel manifolds. Also, zero problems bolting them up to the older engines and only some mild replumbing required.
