On the GM V6s, especially the 60 degree V6s like the 3100/3400, its really the lower manifold gasket that is the issue and its commonly mistaken for head gasket failure. The 4.3 and the series II and III 3800`s are beasts when treated right.
My Impala has the 3.9l "3900" V6, which I understand is just as "bulletproof" as the 3800. It is a proven platform. GM sucks at building any V6 under 3.8l...
With all of that being said... 15 years ago, you could call a guy like me with an OBD tester, and probably get it fixed for a reasonable rate... (I usually charged a 12 pack of Rolling Rock + parts) Unfortunately, technology in most recent vehicles precludes simple solutions. I bought the shop manual for my Impala, and it scares me... I used to work on F-16s...
I hope this all works out. I have owned many different brands of vehicles, and Chevy always gave me the best service...
