Urgent help needed

I just cleaned and reinstalled my lifters in the 318.

They are dry, no oil. When the cam comes up to the top of the lobe there is absolutely no play in the lifter. It's like the hydraulic lifter is completely collapsed. Is this normal?

I checked the dry lash and it is in spec (.060 - .210)

Do I just need to prime the engine by spinning the oil pump drive?

Thanks,
