Thank you guys for the responses. There are numerous questions and ideas posed here so I will comment or answer each one, hopefully:
1. I've tried to remove the sylphon but even after soaking the screws in liquid wrench every day for a couple of weeks, 5 of the screws won't budge. After seeing what it looks like on a separate post I'm not sure of the utility of taking it out at this point since I can just set the louvers open. It doesn't look like it has much to do with the flow in the radiator.
2. I did have a blown head gasket some time back and replaced it with a new one from Olsen. When I was removing the head I noticed a hair line crack on the top. I had it magnafluxed. The only evidence is on the top. I used JB weld in an attempt to stop any propagation, then rigged a test set up to pressurize the interior of the head (to a low value) and detected no gasses escaping. I also have no evidence of water in the oil or anything like that. I know its not optimum, but that's what I've got.
3. The flow tester info you sent Own is interesting. Thank you for that. I don't have a 55 gallon drum of a calibrated flow handle like shown in the picture but maybe I can rig something up.
4. Both hoses are stiff and do not collapse during operation.
5. I live 10 miles out of a small town that does not have a great deal of services and could not get the car to a radiator shop in any case.

I look through the radiator with a light and see that it has several tubes that run straight from top to bottom, although it seems they are of small diameter. Does that sound like the right core or is it possible this radiator has had the core replaced?
