Head gasket repair on 2002 Buick Rendezvous

I have a Rendezvous with 95,000 miles on it. If I pay to have the head gasket replaced along with the 100,000 work done at the same time, 1.) will the engine last another 100,000 miles? 2.) Can I drive it once a year to Florida. Thank you, Patrick

gasket blew due to inferior material used that was not compatible with GM'S dexcool coolant. they should have put a different gasket in that does not do this (hopefully) and you should be fine
