Hyper-V Cluster Network Question

I am in the process of setting up a Hyper-V cluster. Each server has seven NIC cards. I have assigned the NIC cards as follow:

NIC 1 : Management
NIC 2: Heartbeat
NIC 3 and NIC4: iSCSI
NIC 6:  Live Migration
NIC 7: Virtual Machines

If I wanted to dedicate two NICs to the Virtual Machines, what NIC should I use to run two processes on? Is it better to combine CSV and Live Migration on the same NIC or Heartbeat/CSV or Live Migration on the same NIC? Or is there another scenario? I have no more room to additional NICs, unfortunately. Thank you.

I suggest the following:

NIC 1: Host OS Management
NIC 2 and 3: iSCSI
NIC 4 and 5: VM communication
NIC 6: Live migration?
NIC 7: unused

The hosts will use any and all available NICs for heartbeat, so no need to use dedicated for that. I don't even use dedicated NICs for Live Migration, so that is completely optional. I don't know what you mean by a NIC for CSV, because you should be connecting to CSV via iSCSI. For the NICs for Virtual Networks, is you plan on having two separate networks then use the two separate NICs. If you want both NICs on the same network, you should consider teaming them on the host and then attaching the virtual network to the NIC team.
