If you still have stock intake #8 will usually be more lean than the rest.

I thought on the lt-1 one bank runs 2-3 percent leaner than the other.

Reason being #8 intake runner is in alignment with the back wall of the intake. That is the only runner that shares the back wall as part of the runner. The air charge hits the back wall of the intake and goes directly into the #8 runner. The other runners are not against any wall and are not helped with any directional charge.
