Finally something I'm familiar with!
I can't point you to specific profiles, but maybe some suggestions:
- For Dead Kennedys you could look for a Fender Amp with a big Boost in front of it. This is what East Bay Ray used for "Holiday in Cambodia" at least. From then on he hot-rodded his Fender Super Reverb (so essentially more Marshall-style). Later he used a Marshall JCM 2000 DSL with a S-Style Guitar (with humbuckers in it).
Mostly those oldschool '77 punk sounds are kind of clean amps that are turned up to 11 and never as much gain as we use today. So maybe look for some profiles that are a little bit over the break up point, slightly pushed mids and most importantly: play the guitar like it doesn't matter 
back in 77/78 i was using Marshalls , (with no master volume) , and a Les Paul copy (CSL) before i was able to move on to Gibson les Paul customs ..cheers
i'm totally interested as well for those profiles
David G Burns Marshalls on the rig exchange should be good for you, just keep the gain down a bit.. and play hard..
