There are two threaded holes on the back of the head, the machine shop put the CAS adjustment on the wrong side essentially flipping it

ohhhh i get it. So the tab was basically pointing towards the driver side, not the passenger?


I was going to say, the CAS can only go into the cam one way.

Yep exactly what happened! I was so concerned about the cam timing I forgot something so simple. I didn't even think about checking it because I assumed the machine shop put it back on right after hot tanking the head haha....
