lifter install

I've heard debate on this over the years. I didn't soak mine since they get pumped up by oil when you prime the engine anyway. All I did was give them a nice coating and drop them into the bores.
 
I suspect some may be attempting to fill the lifter to help with
valve adjustment :)

Like some said ... you could prime the pump :shrug:

I just dipped em in a large butter dish filled with oil

As for valve adjustment ........
Whether full or empty ... zero lash is zero lash
or
Preload ... if you prefer
