Small parts have a big impact on engine performance.
For example, a good set of lifters will deliver consistent valve timing and maximum power with good oil control. To achieve these benefits, however, you need to make sure you follow the proper lifter installation procedure.
The topic is important enough that Summit Racing created an entire video on lifter installation. It covers new lifter prep, common mistakes you should avoid, and diagnosing lifter issues after installation.

The most important thing when installing new lifters is to NOT soak them in oil overnight.
Install them without oil and adjust the valves. The lifters will fill immediately after starting the engine.
If you are concerned about starting the engine without oil in the lifters, prelube the engine through the distributor oil with a drill and pre-lube tool after adjusting the valves.
