Do all A bodies have overheating problems?

I'm going to throw my 3 cents (due to inflation) in. I have seen too many radiators not getting air to flow through them due to crud(cottonwood trees, etc) blocking the fins. Also, too much paint on the fins. And it doesn't help if you stack coolers. My Old Timer test is: with the car running, hood closed, a dryer sheet should suck itself tight to the grille.
