1967 chevy 292

[heritagewraith]

Good day all. Happy Saturday.
I am putting together all covers on my crate 292. I am curious to which covers I need to put RTV on.
Side Covers-
Timing Cover-
Valve cover-
Oil Pan-

I purchased the finned side covers from 12Bolt. It states on 12Bolt site that I need to clock the HEI Distributor. What exactly does that mean??? I am sure that I am being over cautious. However, I want to do things right. The placement of the distributor is not something I am looking forward to, for some reason.
I am mechanically inclined. I just have not put in a distributor. I am confident that if I do it right the first, I will have no sweat on my brow. haha!!!
