When you say on the top of the runner how close are we talking to where the head and intake ports meet?  My opinion is that you want it on a port as central as possible so the vacuum is coming from all intake paths rather than just one.  If you don't have a intake port on the manifold closer to the carb then a simple solution is to just use a carb spacer with the PVC port as part of it.  This was a standard piece on a lot of Fords.  Shouldn't be hard to find one.

Some picks of PVC setups from the factory. http://mansfieldmustang.com/EnginePCV.html

You definitely want the PCV going to the plenum, not a single runner. The easiest solution is to either use a factory spacer with the brake booster port or find one on Summits website. I know they have them, and fairly cheap (I used one on my truck), but I can't find my receipt to post a part number.

If space is a major issue, about the only other option would be to drill the plenum for a fitting. It could be done without removing the intake if it were done carefully.

I've got a 3/4 or 1 inch aluminum spacer with the PCV tube.
I forget where I got it, maybe an old truck engine.  Anyway, it's collecting dust and it's ugly, but for you it's free, cuz I'm like that.  If you are interested, lemme know I'll take a picture of it.

No problem fryedaddy.  I just live in a really hot area and am more fond of phenolic spacers than aluminum. 
I'd double check your carb tho, almost all of them have a place to put a pcv hose.
