Hello all, I have a question..I remember a mechanic told me that on the old school GM HEI ignitions that when you replaced the ignition module you were supposed to put some dielectric grease on the bottom so the module would not get too hot. Is that something I should do on the module for the 94 Northstar? If i choose to do it will it hurt anything? Thanks for your input and opinions..

Not dielectric grease - IC ("chip") heat sink grease. Radio Shack. White, pasty stuff - transfers heat from the IC/chip/diode/regulator/output transistor(s) to the mounting base/heat sink.

The early Northstar ICM is a stand-alone module which mounts the coils. No transfer grease needed.
