The INVITE string is going to be a method, not a header, so per the SIP wiki section:

https://devcentral.f5.com/wiki/iRules.SIP.ashx

the following may work for that part:

when SIP_REQUEST {
    if { [SIP::method] equals "INVITE" } {
        pool pool_x
    } 
}

I'm not a SIP expert by any means, but pouring through RFC3261, I don't see any specific method or request header that contains "MESSAGE" (other than a Content-Type header used to tunnel SIP traffic).

As for the port, that is defined in the destination port section of the VIP itself.
