IMM Engines 408 build

I've just about had it up to here with hydraulic lifters. I've already had a frick'n nightmare with Hughes roller lifters. Remember this: Hughes "retro fit" lifter not pumping up!

Had to remove the intake AND the Edelbrock head to get the lifters changed out while the engine was still in the car!
Now here I go again.
Anyways... I have a brand new set of Melling lifters that Brian sent.
Is there a way they can be checked before I install them?:(
I don't pump up lifters submerged in oil since I found this on Hughes website "DO NOT fill, pump-up, or soak any hydraulic lifters before installation".
I assume they should know the proper way of doing things.
