Short answer: no

Long answer: It really won't make a difference. If you want to do it, do it. If not, then don't.

extremely insignificant... It passes through about 1/4" of the lower section of the throttle body and thats it. Less than 1" of total surface area inside the 'passage'. I removed mine for the purpose of reducing the possible leaks (2 less hose clamps) and changed the 2 hoses to 1....

Your call.

I would leave it as is, run it to the Radiator. That little system helps bleed the steam out of the Heads. It's not as delicate as a LT1, but it helps.

how does it help bleed? It's got no vent, no surface area to speak of. It's just kind of a high point (more likely to catch bubbles and hold them.

Look at this way, it'll cost you a few bucks in parts, and doesn't heat up the air being sucked in. It's not worth too much thought.
