Breaking down a 4.6 L
#13
Pushrods can be mixed and matched. I know a lot of folks that keep them in order and I used to as well, but I've not had any issues since switching to throwing them back in wherever.

If you re-use those lifters you will also have to use the cam they are mated to. Each lifter has to go back on the same lobe it came off of or it will wipe out the camshaft. Even when swapping a used set of cam/lifters between motors it is a good idea to repeat the break in procedure or you will sometimes still see failures despite getting the lifters back on their correct lobes.

@greisinb and @Alex_M Actually that is not strictly true,you need to have the lifters checked, and possibly re-surfaced and you need to follow the break in procedure. People do put new lifters on to existing camshafts, part of the problem is it depends on each engine's camshaft/lifter setup.
The absolute biggest issue is you must follow the break in procedure lots guys skimp on this and wipe brand new bits

- Brush break in lube on the lobes as well as the lifter bottoms and oil only on the sides of the lifters.
- Before you apply break in lube anywhere, use oil on the lifters and make sure they spin freely in the bores. If they do, set everything up for break in.
- Add a shot of ZDDP to your oil
- Prime the engine before you fire it up and when you start if break it in as if it were a new cam and lifters.
