In my mind I go for the "looks stock but likely has a ton of incorrect parts" looks. Someone at the car show will likely think it's a great restoration.
So what I would do under the hood:
1. Stock valve covers
2. Mopar Battery (I just bought one haha)
3. Get all the decals that should go under the hood like the radiator coolant decal for the rad support, brake booster decal, electronic ignition decal, emissions decal, air filter replacement decal etc... I find those small touches really pull things together.
again i'll add some small print because I feel bad telling someone thier car is not perfect, I love this car.
