It would be helpful to know the year of your Viper.
Look for: Coolant smell during/after driving, signs of coolant weeping down the block, rise in oil level without adding oil, coolant pooling in "V" under the intake manifold...and MY favorite...massive, billowing white smoke out of exhaust pipes...sort of like the "Blue Angels" !!!
I think that you will find that most of us with GenI's pay particular attention to this issue. Service the coolant system REGULARLY (every one to two years at our house), noting that many cautious drivers have replaced the head gaskets before a major problem serfaces...while others retorq the head bolts every so many miles (5000 miles has been mentioned on a Viper driven regularly).
If you are a mechanic, it's not a bad job...but if not, AND you have a Gen I...get it checked now and regularly...in my opinion.
A "search" of this site will reveal a LOT of info.
