Sounds like you rebuilt the monovalve with a kit already? The monovalve is a normally closed open/ close type valve actuated by a solenoid to control temp by cycling at different rates.
Is your coolant level ok? What is your coolant temp? Shut engine after a long drive and feel all the coolant hoses/ radiator and report back the relative temps. That will tell you if there are flow issues. Upper lower rad hose, hose in and out of the firewall are the important ones to feel.
