Deleting Heater Tubing
How would I go about deleting the heater tubing that goes around the lower intake? I am just trying to clean up the engine bay a little more. Could I just block off the port in the water pump and then the two tubes coming from the heater core?

Block them off if you like, take out the tubes. You need no heat in Utah?? imp

Haha nah man, its hot down here. And I just wear a jacket anyways. Why I asked is because it seems the heater tubes are used for flowing coolant in the heads and lower intake. So I just need to know if I would be fine removing the tube, blocking off the water pump port where the tube begins, and capping the two points in the firewall that go to the heater core and comes out.

You need the coolant flowing into the heads, or you may get a DTC that says
Head over temperature warning. You may not need the intake to have coolant
in it, but the heads, must have the coolant. You can add an aux cooler too,
if you wanted to cool the intake and heads down another stage. You do not
want the heat soak, the coolant keeps the intake and heads at a constant
temperature.
You can bypass the heater core, but if the coolant goes to the intake and heads
after the heater core, then you do NOT want to block it. Bypass it, connect
the core input hose directly to the output hose. Do not remove the intake and heads
from the coolant circuit.

Bypassing the heater core won't make any difference. Newer engines don't have the
cooler lines to the heads and intake. The older S97s have cooled throttle bodies
too.
Believe it or not, you want the lines in hotter climate areas, but you don't need the
heater core if you're never going to use heat. Personally, I would install a
switchable bypass, so you can run through the core, or to a bypass hose to the
core outlet hose so the head and intake remain in the circuit, but can shut off the
flow to the heater core.

Thank you 08' Mustang Dude and ZEN357. I do know that the heads and intake need the coolant. I just don't know if the rigid outside heater tube is the supplier of coolant through the intake and heads. I believe they should not be as the coolant should come up from the water jackets in the block and through the heads into the intake. But I really wouldn't know unless I knew exactly how coolant flows in this engine.
