If sticking to the factory design works for you, that's great, but it does not automatically invalidate someone else making modifications to suit their purposes.

Hi everyone. Thanks for your insights. My heat cross over is not blocked off and I do not want to take the intake off to do so. And since I drive the car in the cold weather... I've decided that I will reinstall the heat riser because I think this will help with cold weather operation if the car.
Does anyone know if the original style flange clamps are still available?

Nor Cal... Sorry... Didn't know what to call them but the exhaust shop made the ones that are on there now and they are just flat plates... I thought the stock flanges would work better when I get them to install the heat riser. |

Thanks Trader. I'm going to buy the damper kit and the gasket yes... I was asking about the OEM style flanges though... I just didn't know what to call them. I think this will fix the ticking noise coming from that manifold to pipe connection. I didn't know the heat riser existed or I would've installed all this stuff the first time around.

I have used these Walker "ball flanges" along with stock replacement doughnut gaskets to replace flat flanges just like you have. No heat riser valve is needed, but could be used if desired.

Because I've been looking for an exhaust crossover damper for sometime this interested me greatly. I did some research and found this particular one doesn't have a bi-metal spring, it's just a regular steel spring, so the damper doesn't function correctly, if at all. This taken from reviews I found on Amazon about the product. Now as far as the donut, that could be a very functional one. I didn't read anything negative about that. Is the original part as put on new cars equipped with a bi-metal spring??

To my knowledge ALL Heat Riser Dampers/Valves or Exhaust Manifold Dampers/Valves had bimetal springs.
A list of AMC/Jeep numbers: 3225006, 3238998, 3225054, 3185114. Here is an article on operation and you can see that they were never intended to always be fully opened:
