Setting the valve lash with new lifters?

[Jack's95gt]

I built a 408W from all new parts. I soaked the lifters in motor oil for a day. I still can pushdown the plunger on the lifters with my finger. Should they be pumped up with oil prior to setting the valve lash? If so, would running the oil pump with a priming rod and a drill pump them up?

Yes when u prime the engine the lifters should pump up.

If the valve adjustment procedure is followed correctly, it is not necessary to have the lifters primed when setting lash.

All you are looking for is zero lash + the proper pre-load (1/4 - 3/4 turn).

Just soaking them will not help the plunger absorb oil. While they are in oil, push the plunger down with a push rod or something that will force the air out and pull the oil in as the plunger returns.
