Larry I am curious about this also and Dave I had taken apart the valve bodies to lube them on both my 1000 ng manifold as well as the one LP Jon helped me out with. For sure they appeared to be the same they did not look like what Chris had. They had 3 holes in each one of them but testing the orifice although they appeared to be the same for sure the nat gas was larger when I tested it with a piece of wire. My eyes ain't what they used to be, what I did not do is try to test the hole size on the brass valve body since my guess is they were larger but I sold that manifold.
Not sure if this made any difference either but the LP manifold has at least mine does like a bulge on each end of the valve piece ends where the nat gas was flat it for sure looked different. One other thing the burners were pretty tight to the orifice stops on the nat gas where there is plenty of room on the LP not sure this means anything.
Larry hope your are not mad at me anymore I truly was not trying to offend you.
