Overheating issues

x2 yellow rose . I have the same issue . Not solved completely but getting there . I have a BB with a 22"A/C rad . What helped is : high flow thermostat , high flow water pump and fan clutch . thermostat is 160d. It all helps . If you want to make your own shroud you need sheet that is .060"-.100". My next endeavor is a pulley change . Don't give up , you can solve this .
