Check your total timing/full advance.
20 initial would more than likely make it run cooler at idle and not hotter.
The fan ,it needs to be about 3/4 -1" from the radiator, not 2, or it will run hot till it gets moving through air 'at speed '.
Pcv hooked up making it cough here n there could be a blow by issue or maybe you are not readjusting the idle mix screws afterwards?
