Auto-Lite 2243 for the colder plug which was the original for the M38 and Auto-Lite 2245 for the hotter plug which was the original for the M38A1.

Would running 2245's in a L143 that is bored to 80 thousands be bad for the engine over time?

I don't see how it would unless one is running radical fuels or compressions.
