According to my service manual, the conical washers are placed on the studs on the #2 and #8 exhaust ports, but none on the #4 and #6 ports. Unfortunately, it only speaks of the passenger side. It only mentions the torque specs for the driver's side. No mention of the conical washers for the driver's side. Would it be safe to say that those washers would be on the #1 and #7 cylinder ports?
