I recently acquired a relatively new HEI distributor from a freind and it was in great shape, but I took the module and advance out and cleaned it up a bit. When re-installing the HEI module is it a thermal grease under it or is it just di-electric grease like you would use on your spark plug ends? The guy at napa said it was for corrosion and dielectric was fine, but I know its for heat. What is it and do you have a part number?
