Parts list question

[Happy_dan]

I am going to pull the motor from my 68 C-20 327 with TH400 this winter to try and eliminate any oil leaks.

Any suggestions on what to replace? I feel like I am missing something from this list I made or tricks of the trade that you would share. I have read a lot of thread about the oil pan gasket in particular but assume if I order a pan from Summit, I will know exactly what gasket to get with it. looking for any advice here since I am new to the truck. I have always owned newer vehicles and always have done my own work so I have learned having the right stuff and advice from experienced folks is invaluable.

One piece Felpro oil pan gasket
Rear main seal
Valve cover gaskets
Timing cover gasket
