Kahn,
Southern Automotive sold me an expansion tank, and suggested that the restrictor would never get stuck closed. I decided to remove the restrictor, and run the 180* stat so I could be sure my aluminum block came up to temp quick, and stayed there. I had to have the tank machined to accept the t stat once the restrictor was removed, and then have the tank repaired, when the machine shop got finished with it. I have a 180* stat, with a 195* fan switch. I might even use my heater, or demister, if I ever put a top on it.
Do you live in a warm climate?
For your Hurricane, I think you'll need the shortened neck on the tank.
