If the dealership did the work, chances are they used the newer design gaskets as they have been out since 7/02. If an independant shop did the work, and they bought the parts at the dealership, see if they list the gasket part # on your invoice. the number for the new gaskets is 89017279. The mechanic was also supposed to replace the intake manifold bolts with new ones from GM. They have a pre-applied threadlocker on the bolts. Their part #'s are 11588915 for the shorter bolts, and 11588914 for the longer bolts.I would go back and ask them if you are unsure.
