I suspect leaking isn't common. Patrick's link has some good suggestions on sealing the plugs.

I noted one guys comments that the screw in plugs were to make the block stiffer.

That makes sense. Ford had bottom end issues on 427s in NASCAR. A screw in plug costs more, but if it allows you to win races on a low volume engine, then that is a good reason.
