Very nIce write-up, Matt,
Here is an earlier thread on this topic. Denny Graham has posted a nice description and a lot of nice photos.
I double if a sealant was used around the grease plug threads (into the distributor), but I doubt that using a sealant would hurt anything.
I have never seen grease come out around the threads. It seems there would not be enough pressure in there to force grease out around the threads?
