Be careful on the intake gaskets. If the Fel-pro gaskets you get are plastic take two steps back and run away fast. Go over to the closest GM Stealership and get the metal intake gaskets. Part of the issue was that it was a rubber/plastic composite gasket that did not hold up due to the heat and stress. GM made a metal/rubber gasket which is so much better. I have had one on my 2005 LeSabre for years and it is great.
If you get a plastic/rubber gasket set, you are going to be replacing them again down the road.
Good luck with the car
