As per
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A1/configuration/security/guide/tcpipnrm.html#wp1075741
"Disabling TCP normalization affects only Layer 4 traffic. TCP normalization is always enabled for Layer 7 traffic."
By disabling TCP normalization the following Layer 4 connection parameters are ignored.
exceed-mss-----Configure behavior if a packet exceeds MSS
random-seq-num-disable----Disable TCP sequence number randomization
reserved-bits-----Configure Reserved bits in TCP header
syn-data-----Configure behavior for a SYN packet containing data
tcp-options-----Configure TCP header options
urgent-flag-----Allow/Clear Urgent flag
I think you will need "Set timeout inactivity xxxx" command even if "no normalization" command is defined.
