Welcome to the club forum and the KFOCI! When new, the engines were designed to run on a lower octane fuel that, of course, had lead as an additive. Since lead is long gone, we today try to substitute other chemicals to make up the difference. I would assume your engine was not rebuilt with hardened valve seats so you may want to add something to the fuel to aid in cushioning the seat if you plan to drive your car more than just occasionally. Myself, I use Marvel Mystery Oil. I add a few ounces with each tankful and so far, so good. I'm sure others have what works best for them so we'll see what they have to say.
By the way, post a picture or two of the new car!
