Lifter replacement

On my 340 I fired it up on an engine start stand broke it in.
Started it a couple times after that, everything ok.
Let the engine sit for 3 years.
Re-primed the engine when I set it in the car, it fired up quick.
Peck-peck-peck, I shut it down after a few seconds after verifying good oil pressure.
The exhaust lifter on #8, the plunger was stuck down, and did not pump up, bent the push rod, and trashed the rocker arm.
Lesson learned, do not leave an engine with tension on the rocker arms sitting.
I replaced one lifter, push rod, and rocker arm, to this day it has a slight tick-tick-tick that you can only hear with the hood up.
The cam felt good, but I got a gut feeling its not going to last.
