Probably about time-rocker adjustment

Bent pushrod, don't know if solids or hyd...... pull the intake so you can work on it easier and check the lifters, potential cam damage, and check for correct pushrod length for sure.

If in good shape, order pushrods, install a timing tape on the damper and use the Direct Connection crank rotation method to adjust rockers.

Definitely solid lifters. Removed them all and only found the 1 exhaust valve pushrod on #1 cylinder being bent. Planning on ordering a new set of pushrods and learning how to adjust the valves myself. Can add this to my list of firsts since I've owned my car 5 plus years.
