LA 360 Engine refresh?

I don’t mind it. It runs well. There’s a slow slow oil leak up top somewhere and I’m cleaning up the engine bay, so I figured I give it a refresh and learn a few things in the process. I’m very much a novice and bought this car as a project to keep me sane while being a stay at home dad(******* Covid). I’ve been watching a ton of videos, reading tons of online articles and how to’s and I’m inspired to take the jump and improve this ride myself. Also, since I don’t know anything about the engine build and I’m curious to know what I have. I’m also changing the 7 1/4 open rear to an 8 3/4 sure grip 3.23 and have been told that I may want to change my cam.
