change the gaskets with it and make sure you don't put it in backwards. Also consider a coolant flush.

Those trucks have all aluminum heads and intakes. This can cause you problems when your trying to take the thermostat housing off. Aluminum likes to corrode really really fast and it is quite common to actually break the bolts off. Unless you have the tools to fix it if they do break, I would leave it to someone who does. Pm me if you would like me to do it for you.
