Have anyone replaced their radiator with the heavy-duty one. If you have, did it make a difference with the motor overheating?
 
I have bought Snyder's "heavy Duty" radiator twice. each time it solved the overheating problem. In each case I was replacing a worn out original radiator.
 
I bought a Bratton's heavy duty radiator for my 28. In Florida the weather is always hot. The new radiator fit great and solved the running hot problem. In fact, it may actually be running a bit cold especially on days that don't go above 80 outside.
 
When I buy a radiator for one of my model A's I buy the eight fins per inch version . more fins per inch cools better . I usually want every advantage that I can get .

What about the one that is ten fins per inch. How much better would it be over the eight?
 
one should look at combination of number of tubes AND fins per inch. Each contact of fin to tube is a point of heat dissapation.
 
The 10 fin radiator should be even better . I don't think that the vendors that I dealt with had the 10 fin radiators at the time that I bought mine or I would has have got the ten fin .

Model A radiators are very expensive now days . The new radiator that I bought for my 31 coupe in 1990 was only $180.00 . This is a three row radiator with 6 fins per inch and has never over heated .
 
A new Brassworks HD radiator made no difference to my car. Still overheats in high ambient temps, just like the old one. That is a stack of cash I won't get back!
 
I would think that you've got other mechanical issues then, i.e." timing, plugged block, w/pump. Most that replace with Brassworks or other quality cores have trouble "warming" them up. FWIW
