I've done this kind of work more times than I'd like to remember but here's the gist of what you'll need. Some of this is overkill, but ensures that the probability for failure will be minimal.

Upper/Lower Intake
Fuel Injectors
Heads
Camshaft
Timing Chain Assembly
Upper/Lower Intake Gasket (you should of gotten this with the intake)
Lower Intake/Head Gasket (you should of gotten this with the intake)
Head Gaskets (made for aluminum heads, yes they are different)
Timing Chain/Waterpump Assembly Gasket Kit
Valve Cover Gaskets
Stud Mount Head Bolts (don't get plain bolts, and DO NOT reuse stock bolts)
Waterpump/Timing Chain Bolts (stock bolts have a tendency to rust to the point of not being reuseable, mine were fine, but most aren't)
Lower Intake Bolts (same as water pump, some bolts can rust and may not be reuseable, in this case mine were toast)
Throttle Body Gasket
Head to Header Gasket
Thread Ease (for all non-water jacket bolts)
Thread Sealant (for all water jacket bolts)

Tools Needed
Flat Head Screw Driver
Phillips Screw Driver
Fuel Line Removal Tools "oval plastic things" (to remove the fuel lines from the fuel rails)
Metric & Standard Socket Set in 1/4, 3/8, and 1/2 sockets from up to 1 1/2" sockets and extenders
Torque Wrench
Pulley Puller
Adjustable Wrench
Metric and Standard Wrench Set

While you're in there this is a prime time to change out the TPS sensor, EGR, IAT sensor, and thermostat sensors. You will have to remove all of these during the process and it's just wise to change these out if they're still the original that came in the car.

 

Hey; Whats the 1 1/2 socket for?

 

maybe to tap the timing cover seal in??

 

throw in a set of roller rockers, and be sure to double check your pushrod length if you do. Also check those lifters.
