I don't know about yours with four hoses, but mine comes out of the valve covers on the forward side, about halfway up. In my limited experience, hose clamps and standard rubber hoses are fine (if that's what you've got, you should be okay) because there's no real pressure in the lines -- up until about 3,400 rpms or if you have too much oil in your engine -- compared to the lines to and from a remotely mounted oil cooler. Unlike an oil cooler, there isn't a pump pushing the vapors up these lines.
The breather box is a pressure outlet for the crank case, with the holes in the valve covers allowing for oil to blow out and slowly drain back in gravitically. The oil will drain back through when the rpms that pushed the oil out are lessened, so those lines need to be a downhill travel from the box back to the valve covers.
If you take the top of the box off, there should be a spongy filter and a perforated plate inside. Every now and again, take the sponge out (that's a baffle, just like the metal plate, intended to keep oil from frothing out of the box) and wash it out in a butter tub of gasoline and thoroughly air it out, put it back and it should work forever.
I haven't ever seen a second pair of lines except on a car with a turbo, so the supply to the turbo would have a drain also; no idea where yours might go other than the valve covers. Got photos?
