a Frenchman who needs advice for GM HEI MODULE!!!!
The key to making the HEI modules last is heat management. You need to attach them to a good heat sink. Since you are in Europe, look for a Marelli Plex 201 equipped early 80's Fiat, lancia or Alfa Romeo. They have a really well designed heat sink and coil mount combination unit that uses a GM style module. Too bad they're hard to find in the US.
