On pushrod engines you want adjustable pushrods when using rocker shafts to adjust for wear, or standard pushrods with adjustable rocker studs. The advantage of rocker shafts is that they are much stronger and handle high rpm much better. down side is they don't tend to flow as well as studded rockers.
With pushrod engines there are 2 main types of lifters (flat tappet and roller). Flat tappets were used extensively until the 80s due to the decrease in friction with roller lifters. The advantage of flat tappet design is they tend to give you better lift, while also increasing wear (especially with very high performance grinds)
More things will come to mind, but this is all I can recall of the top of my head
