It actually goes "in reverse" of what you said! <grin> The plug near the fuel pump is the pressure side and, of course, the #4 and #5 mains are in the rear of the block, so the pressure up front is ported to the rear of the engine at the location where the oil pressure gauge tap is located.
I've never used one, so can't comment on whether they work or not. I've ran a lot of Clevelands, so maybe it isn't necessary? I kind of like not running one so that way I know how much pressure is really getting to the rear of the engine...but I'd rather not know and never have a problem due to the lack of pressure either!
If I was going to do one, I definitely do it up in steel line and not braided hose. The steel line will allow you to route the line very tightly to the block, under the extractors and up the back side of the block. I don't think that this "trick" alone is worth anything, but there are those who swear by it. If you want to do it right, you'd need to plumb the oil passages under the inlet to directly feed the mains...and that starts to be a full time job. The question is whether or not it is something that is even needed for what you're doing with your engine.
