the rusty nipples are coolant lines. leave those open.
there is another nipple under the #1 and #2 runners and a nipple on the metal coolant pipe under the rear runners, join those 2 nipples together w/ a 3/8" fuel hose and clamps.

this will keep coolant from circulating in your ISC and TB and keep it cooler when driving. wards off heat soakery.

so your saying the ISC is left open and run the lines from the head back into itself. but what about the throttle body?

by-pass those lines as its to heat the throttle body up to help keep it from freezing (iirc) and simple heats up the intake air. just by pass the lines
