Putting in new lifters - what do I need to know?

Old lifters are out, none of them have dished bottoms, so happy with that. New lifters ready to go in once I've sourced some assembly lube.

What do I need to know about this? Do I just slather the lifters in assembly lube and push them in? Do I need to fill them with regular motor oil? Should I beware of pushing them too far down into their bores, or can that not happen?

All advice appreciated!

So what does pumping them up actually involve? And do you not bother with assembly lube?

I'm confused now. Googling about installing lifters (speaking generally, not Jeep-specific) brings up contradictory information - one side says you *must* soak the lifters in oil before installing them, the other side says it's completely unnecessary and can actually cause problems if the lifter is already pumped up when you first start the engine

No engine builder by any means but unless the lifter was locked up somehow I don't see how it could cause damage. Its basically a way to open valves and pump oil isn't it?

You take a container like a butter tub and fill with clean oil, set the lifters in on end completely submerged in oil and use a pushrod to pump the lifter expelling air and priming with oil, then you slather the lifter will the prelube and install, get plenty on the bottom of the lifter and cam lobes, when you start the engine run the rpms up to about 2K which provides oil splash from the crank throws to bathe the cam in oil, don't let it just sit and idle more than a minute, then go drive it.
