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.

Did you all cap the TB openings where the hose passed through?

^^You don't have to do that..some Coolant might come out when you take the lines off..but there is nothing there to worry about.

I just wanted to make 100% sure there wasn't a chance of a vac leak
