No - the way that I have everything routed works without the bypass.
Currently I have a line from the lower intake to the heater core, then back to the rad (factory setup), except I do not have the restrictor valve in place. This allows the coolant to still go through the system at a slower pace and does not overheat the motor. Similar to the bypass, but larger scale. I have been running this setup for 6 years.
