LIM Gaskets...as in the Lower Intake Manifold...
You'll need...
GM Aluminum Intake Gaskets
2 Coolant Elbows
Upper Intake Manifold Gasket (Rubber)
Throttle Body Gasket (Rubber)
Bottle of High Temp RTV (I use red on everything...but I'm just lazy

)
Then...drain the rad and flush out the Dexcrap and replace with either the green or yellow stuff...IMO...since they are cheap I'd throw a new T-Stat in there too...just a stock 195* one too. While everything is off up top I'd swap the pumps out then that way you can reach down to the pump a LITTLE easier...plus...I'd knock it all out at once and do plugs (Autolite 606's) and wires (Lifetime warranty replacements from your local auto parts store) too...with a new air filter.
Then again...that is just me. But welcome anyhow...the PS Bolts...are 13mm...and you gotta line up the hole in the pulley to remove the bolts...kinda a PITA...but that's FWD V6's for ya!
