Yes, they will all work. This is what's called a DIS coil for all GM cars using these type coils. As far as supposedly high performance verions, there is:

1. The MSD
2. The Accel
3. The Summit
4. The Jeggs

All 4 look like pretty much the same thing, all with brass terminals. They are probably all 4 made by the same place. The Summit and Jeggs versions are the cheapest.
