Re installing hydraulic lifters.

I am re installing my cam and lifters.
Is there anything I should do to properly re seat them?

I had planned on just oiling them a bit, dropping them back in the holes, in order of course, and then installing the push rods, setting the lash, etc.
I used assembly lube, on everything. Will they fill up properly with with just priming?

Then reapply lube, when I close up the top end?

If you put them back in the same holes, they'll work. Did you do anything to empty them? If you just pulled them and put them in a tray, they won't need priming. Just lube 'em up and re-install.
