I had the pcv valve running to the big port on the back of the carb normally used for the brake booster but since I didn’t have one I though the pcv just needed a vacuum port so I put it there
Where is "there" ? , and Where is it now?
OK, I still can't tell exactly where you plumbed the PCV system to.
So, One more time; the PCV has to be plumbed to the FRONT of the carb,
on the nipple that is there for it, that splits and exits just below the two primary throttle valves; as shown in your pic in post #39..
If you install it on the back of the carb, it will act like a vacuum leak, and wreak havoc with your Idle-AFR. .
