In general Viper's are easy to work on because they are disc brake push-rod engined cars. Exotic in performance, but not technology (until the 600 HP Gen IV engine arrives later this year) Only dif from your vette is fuel injection is a bit more modern, and you'll need to get a few metric tools
The later the model, the more complicated and inclusive/integrated the electronics become. Parts tend to be high, but several used or discount parts sources are available: Parts Rack, Tators Dodge, Woodouse Dodge, X2 Builders, Larry's Viper Parts, Roanoke Motors, etc. Also read these forums and you'll find out which other Chrysler vehicle parts will work on Vipers
Gen I - simple push rod V-10, minimal electronics, non-abs, no OBD II, no power mirrors or windows, no airbags, single O2 sensor per side, pretty much a big engine with only the parts needed to "go-fast" attached.
only real issue - need to go to mls (multi-layer-steel) head gaskets as mentioned and many parts are already "No longer serviced". suppliers such as DC Performance, Archer, etc. are starting to make some parts/alternatives needed they become unavailable or as factory prices become "high" - water pumps, A/C condensers, etc.
'96 Gen 1 - added OBD II
Gen II- '96 GTS -97 RT/10, airbags, power windows
later Gen II's added ABS, power mirrors, airbag cutoff switch
Gen III- became a much more refined car, engine still a V-10 push rod, just bigger
Gen III.5 Engine is going to be a very complicated V-10 pushrod with variable exhaust timing (cam within a cam) and all the associated pumps and electronics that go with it.
