Yeah, That always worried me as well. Here is what I ended up doing.
So far, the O-ring works great, no leaks.

Hey BigDaddy,
I have a question regarding the throttle-body or anybody else can chime in, I'm in the process of cleaning up my thottle-body as well, but i notice in your pics, you have cut off the outlets for the coolant lines instead of capping them, I know it looks alot cleaner, were you planning on filling them in? just curious, if so, with what? Thanks

I used to tap those holes with 1/8" NPT tap and put plugs in them, that leaves a clean installation. But when it gets right down to it, you can't see them when the TB is on the car, so I started leaving them off. Less weight hanging off the front of the car

That looks similar to my front cover that I tried to drill out to 1/2" on the feed. Hit air just like your pic. You gotta hate that.
