Like the bypass line Marc Haibeck sells? Wouldn't I also need to block at the injector housings to get the full "easier and quicker"?

Not meaning to get off topic, and certainly not arguing w/ Marc Haibeck, but I drilled and tapped and plugged the TB coolant ports at the IH. To avoid any air bubbles, I remove the cap from the side of the coolant pipe (drivers side) and fill the system there. I've done this a few times now, and haven't had any issues with air bubbles.

That said, Marc's method came to light AFTER I had done the plugging method. And, to do it over again, I would likely go that route instead of plugging the IH. But, either way REALLY makes pulling the plenum a SNAP!.
