Is there a pattern when I torque the exhaust manifold down? How many foot pounds? Thx.

Start in the middle and work your way out. Go hand tight. 30 ft-lbs. would be a nice round number, but I don't get carried away with torquing simple things.

No worries... wait, you asked for the torque specs too... hang on a sec...

INSTALLATION
(1) Using new gaskets, install the exhaust manifold
and gaskets. Install the bolts and spacers and
tighten the bolts in the sequence shown in to 43 N·m
(32 ft. lbs.) torque.
(2) Retorque the four center bolts.
(3) Install heat shield and torque nuts to 15 Nm
(11 ft. lbs.).
(4) Install cab heater tube.
(5) Install exhaust manifold bolt retention straps.
(6) Install the cab heater return hose to the manifold
bolt stud. Tighten the nut to 24 N·m (18 ft. lbs.)
torque.
(7) Install the turbocharger and a new gasket.
Apply anti-seize to the studs and then tighten the
turbocharger mounting nuts to 43 N·m (32 ft. lbs.)
torque.
(8) Pre-lube the turbocharger. Pour 50 to 60 cc
(2 to 3 oz.) clean engine oil in the oil supply line fitting
on the turbo. Rotate the turbocharger impeller
by hand to distrubute the oil thoroughly.
(9) Install and tighten the oil supply line fitting
nut to 24 N·m (18 ft. lbs.) torque.
(10) Position the charge air cooler inlet pipe to the
turbocharger. With the clamp in position, tighten the
clamp nut to 11 N·m (100 in. lbs.) torque.
(11) Position the air inlet hose to the turbocharger.
Tighten the clamp to 11 N·m (100 in. lbs.) torque.
(12) Raise vehicle on hoist.
(13) Install the oil drain tube and a new gasket to
the turbocharger. Tighten the drain tube bolts to 24
N·m (18 ft. lbs.) torque.
(14) Connect the exhaust pipe to the turbocharger
and tighten the bolts to 11 N·m (100 ft. lbs.) torque.
(15) Lower the vehicle.
(16) Connect the battery negative cables.
(17) Start the engine to check for leaks.
