There is another way to do it that we found to be consistent. We leave the hose attached to the water pump. It's actually VERY helpful. I have a race motor so this thing is constantly being taken apart. It's very easy to do with TWO guys. We leave the top end on the manifold, although if you want to remove it; be my guest. It's not really necessary. We don't use the corks either. They're a pain in the ass and are subject to shift. I don't know anybody using them around here anymore, including Keith Craft. All you need is one clean, consistent bead across the front and the back. We tack the manifold gaskets on the head side and they will not shift when you drop the manifold in place. The bypass functions as a "perfect" CENTERED guide to place the manifold down. We tilt the front end into the bypass hose to it's last point and "set it down". Nothing moves! Stick a bolt in opposite corners of the manifold "in case" your a tad off. Without the corks there, any adjustment is so miniscule it won't break the seal because there's no corks to shift. I have done it 4 times these season and have never had a leak. Everything else may leak on my wheel barrel, but not the manifold. It's not rocket science and is really simple. You only need a helper for 10 seconds for balance and to help you guide into the bypass hose. It's truely not a big deal.
BTW: RTM442's idea sounds interesting. I have never done it that way, but we never needed too. Frankly; we use the hose as a guide for placement and we can see the ridge in the bypass hose where it was last seated. the dam thing is so short and not very flexible it hadn't occured to me approach it that way. Anyway; you have a couple of alternatives. Regardless; I'd dump those stupid corks. They create more issues than they solve.
