Well, unless they left a perfectly smooth machined surface that happens to be almost the exact diameter as the holes in the exhaust manifold when they were broke then no they are guide pins. I also have a 6.0L from a 2000 2500 and it has the same pins in it as well. So apparently some off these engines did in fact come with guide pins. I will take some pictures tonight and post them on here.
