I'm sure the correct answer varies from person to person. My car runs the cooling fan whenever the AC is in use, so I doubt heavy blocking affects performance much. If you see your engine coolant temps running much hotter than they are without the block, then too much blocking is being used. My car used to run 185 temps, and now run 190. Seems to be the perfect amount of blocking.
