F5 will not add last-modified headers unless you have additional profiles attached. You will need to check if the 304 message is actually being sent to the client. Use tcpdump and wireshark to confirm this.

    Thanks will try to capture tcpdump. But the weird thing is it only happens when F5 is brought into picture and access server from firefox browser. When we access server without F5 in between it never happens.

    I'm surprised if it modifies any headers. It should just pass them through. A tcpdump capture client and serverside should confirm this.
