Don't know if you resolved this yet but I'll play too. A rusted coolant baffle will disturb the circulation as engineered. The radiator flow rate is supposed to be like 50 gal per minute. So if you dump 5 gallons of water in and it flows out in 6 or 8 seconds? Radiator OK. Let's assume you have flow at all and set any water pump discussion aside.

So far we're at check for a rotted baffle plate and I'll assume you can put a finger thru that rectangle hole and see it in the other one? Let's hope so.

Now let's get to an often overlooked issue. Hows the ignition timing? Late ignition has been "salesman of the month" for radiator/cooling systems lots of times. If the timing in off 3 or 4 degrees its gonna run hot. Might idle ok, a little warm, but load it and it's ready to make coffee (!). Worth a look. I had an old pattern for the 34 baffle and used to whip up a new one out of thin stainless. I think there's 5 holes in it, and the idea is to even out the coolant flow on those long motors. To put us all at ease (although it's been a while) I think there was a separate baffle in the "pack" for the oil cooler. To explain, cooler, gasket, small baffle, gasket. I'll check my parts book and admittedly I'm peeking thru memory cobwebs. That's all for now...
