That would be great if my tapping noise was your O2 plug.

Is there any chance that this might be coming from the trans, or torque converter? It is rpm dependent only, not speed. It will do it in park.

those pushrods are definitely too long. Comp recommends a 7.425 pushrod with their XER grinds.

I'm avoiding everything, with 23 degree weather and nowhere indoors to work on it.

I guess non-response to this question means no.

Besides, even if the pushrods are too long and making the valvetrain noisy, how could they be the cause of this new noise, with its tick,tick, tick, nothing, nothing, nothing, tick, tick, tick cadence?

one could have bent and is rolling maybe?
Maybe your knock sensor is doing a test.
Or your builder was a midget and he's trapped under the intake.
