440 rear main seal... thoughts

The originals work fine, I always first check seal alignment with the crank out of the block and never use the side seals. Just silicone injected with a syringe that has a small juice box straw stuck on the end of it down the sides of the seal block. Push it to the bottom and inject the silicone as you pull it out. You can see it if you look through the side gaps as you do it.
Line honing won't cause seal issues either.
Unfortunately, when you ask a question around here, you're going to get suggestions from those who have a clue and from those who don't.
