How many miles of driving do you have on these new lifters/cam and pump? Getting all the air out of new lifters especially if the adjustment was a tedious affair, may take up to 20 minutes of sustained driving. If you are well past that and you hear a clicking, it may not be lifters making the noise. Can you determine any change in intensity between hot and cold?

Good thing I am not a airplane landing advisor.

"Tell me your altitude."
"Oh, we crashed last week."

Why push rod? Let's narrow it down with a stethoscope (12" 3/8 drive extension or something)

You can verify if the lifters actually have all pumped up by performing a check in the same sequence as a valve adjustment.

Just check for any movement if you pull the adjusting screw and push firmly on the lower part of the pushrod. Movement is evidence of a soft lifter.
