Schrade, According to the LT5 service manual supplement the torque spec for the IH is 19 lb ft . Be sure to secure spark plug wire harness retainer with injector housing rear bolt on right and left sides. should be in your pics somewhere.
Coolant outlet pipes are 89 lb in.
Fuel rail to IH is 19 lb ft
Manual doesn't specify re-torque after installation so I would make sure you hit those torque numbers on the money with your torque wrench. At least 3 circuits around. There is no sequence in the manual as where to start but I do center out in a circle.

Note: these torque specs for the IH and fuel rail is different in the general engine section 6. That section indicates 20 lb ft instead of 19 lbft. Strange.
