1999 Chevy Tahoe smells of antifreeze from tail pipe

I own a 99 Tahoe and recently I have found that the exhaust pipe blows white smoke with a hint of antifreeze smell coming from the exhaust. Could this possibly be the Intake gasket going bad? How hard is this to change for the village idiot? It is a V8 - 350 Vin R with 130000 miles on it. Any help with this problem would be greatly appreciated.

If the Intake Gaskets have never been replaced, then the chances are very high that is your issue.
