disconnect negative battery cable
drain engine coolant
remove vortec cover
disconnect accelerator and cruise control cables
unbolt bracket back cover bolt attaches to
remove iar cleaner duct tube
remove coolant hoses from trottle body
remove vapor vent tube from throttle body
remove egr pipe from throttle body
disconnect bracket holding wire harness to top of intake
disconnect connectors for 8 injectors, idle air motor, throttle position sensor, evap purge solenoid, map sensor
disconnect purge solenoid vent tube (squeeze retainer)
disconnect fuel lines
remove brake boost hose
vemove pcv valve and hose
remove intake manifold from engine
install in reverse order
intake manifold torque specs
44 inch lb first pass
89 inch lb final pass
all other small bolts are 89 inch lb
think that covers it,
have fun,
good luck

There is no need to do most of that stuff. You should be able to pull the bolts holding the intake to the motor and lift the intake enough to unsnap the old gaskets and snap in the new ones. I could do it in 15 minutes if the engine was cold. (but I have had the motor in and out of my truck 10 or more times)

dont bother draining the coolant leave the by pass hoses on you will lose minimal coolant if you loosen the cap. little messy but for me time is money.
also ask your dealer to get gasket for z-motor 5.3 they are redesigned gm is replacing when they run out of stock. new gasket is green rubber in black plastic
