Go to a cross flow design (tanks on each side of rad) and use an expansion tank
in the system. I'd route water out of the heater port in the top back of the
head to the expansion tank then from bottom of that tank to the heater return
on the back of the water pump. I've done this on a endurance race TR 6 and ran
great temps all weekend in the Texas heat. No fan required.
