They look ok. O2 volts at a 65 mph cruise are not all that important as there is not much load on the engine. You want to take your readings at WOT and monitor knock retard along with it. The O2 volts are supposed to go up and down at cruise

That's normal. You are in closed loop at light load. Your O2's are supposed to cycle.
