Do the 2000 and newer cars have the same trouble with head gaskets or did they make changes. I thought I read some ware that they improved the design?

The head bolts where lengthened in 2000 and HG failures fell off (though not unheard of). In 2004 GM went to a coarser thread pitch and failures seem to be rather rare after that.
