The LT1 cars use reverse cooling, no issue with overheating that I have seen. If a car runs hot, I would check to see if the cooling system has been properly flushed and maintained.

Good luck!
AC Delco Optisparks are rebuilt and most likely won't have the Mitsubishi optical sensor. All of the new sensors made today are knockoffs from China. The only new ones available are from aftermarket sellers and they will have the Chinese sensor.
