Opines or facts please

I have this Holley version. If your saying it has plastic type inserts at the mount holes then they must have cheaped it down (or maybe they are better) a little as the one I have has aluminum inserts like shown here. But it works (along with other things I’ve done to thwart heat soak) in my oppressive oven of a dog house environment.
As you can see the shield extends front/rear under the Holley bowls. Still holding up almost 4 years later not separating or falling apart. I do use gaskets on both sides because I want to.
