Bite the bullet and spring for a new radiator! It will either solve the problem or at least eliminate one of the possible causes! Old round tube radiators (especially the 28-29's) were marginal at best when new. No matter what you do to those eight decade old cores, they will never be as efficient as when they were when new and they weren't that great then! I ordered a radiator from Tam's a few years ago on a Monday morning, it was delivered Tuesday afternoon by UPS and I installed it that evening! All my over heating problems vanished and the engine ran so cool (130 degrees max) I had to install a 180 degree thermostat (the 160 degree one I tried first barely raised the coolant temp)! Believe me, I did everything practical to that old round core radiator, but it persisted on having uneven core temps even though it passed the so called flow test easily!
