Your absolutely right, and applications that were designed with the one piece gasket from the beginning, I don't have any troubles with, it is specifically the "retro" gaskets that give me trouble, and I am no novice in sealing an engine up, I HATE even as much as a seep, where-as some builders accept some leakage.
As far as sealing up the basic 4 piece cork gasket, I glue the cork down w/ some weatherstrip, I put a little RTV under and on top of the end seals, and as of late, I have been "wiping" a small amount of silicon on top of the cork, but I do not tighten the pan down fully until the silicon cures, I pull it down about 50%. This method has been yielding me ZERO leaks!
