I didn't have to do that.

Just make sure you don't remove the solenoid, with the four allen bolts. Just remove the whole assembly off the back of the head and you'll be fine.

When re-installing leave the two screws a bit loose on the sensor so the ecu can adjust the timing, then you can tighten them back up. (this is the sensor on the back of the VVEL housing that can rotate a bit)

And what if I had to replace the solenoid from a broken connector?
Long story short, I had to change my block, th motor came with a broken VVEL solenoid connector, we replaced the solenoid (black top with the 4 Allen studs)and clocked it the same way it was in.

Do I need to readjust anything after?

you will know if you log the bank fuel trims. if one side has a big afr correction it could be the actuator out of position.
