It is my observation that one can simply turn the intake manifold 180 degrees (clockwise or counter, doesn't matter!) and it will bolt right up pointing the throttle body in the opposite direction of stock. The fuel lines are then wrong then but no biggie. The real trouble is you now have to figure out where else to mount the alternator. Also not too big a deal though, particularly if the AC isn't going to be used.
I think the rationalization runs like this:
A) Slap on a $10 elbow (works OK, kinda cobby looking, can't see it most of the time)
B) Rotate intake 180 degrees, fabricate throttle hook up, remount alternator, and re-plumb fuel lines (works great, looks great, can't see it most of the time)
If you only want to milk the cow once choose A. You, Sir Edward of Metal-Work, Pounder-of-Thumbs, Coverer-of-Speedster-Cockpits, care about things. You would choose B every time. That's why there's a long list people that would like to share a beer with you. Bookmaker's odds say John's list is really short.
