Its about stopping thermal transfer, you really want phenolic gaskets or washers.

I just asked on FB from some of my tattoo artist friends to see if they have any. Side note, is that a vac gauge on your VC plumbing? That's rad. Gives me an idea to attach one to the catch can setup I'm working on.
Yes vac gauge to see how hard my custom catch can is scavenging the motor under full boost on the dyno.
Eventually I'll put a sensor on it and do a pod gauge in the factory ashtray.

Nice! I've got 3 innovate gauges going in my ash tray. Oil Temp/Press, Water Temp/Volts, and the ECF-1 (ethanol %, fuel temp, fuel press, wideband lambda)

Agreed. I just added the phenolic intake manifold spacer and it reduced the aluminum manifold surface temperature from 150f to 120f. Holy smokes...
You what I would be interested in? Somebody should make anti-thermal bolts, studs to use with these phenolic spacers and gaskets... oh man, then there'd be even less heat transfer...right now, I know there's less, but still the metal studs and bolts are still transferring engine heat to all connected parts...however slight, it still doing it via direct contact.
Also... this is proof of my OCD and lack of financial smarts... got laid off from covid-19 pandemic destruction and still buying any parts that help with engine cooling... go figure.
Extremely simple. Buy some phenolic gasket material, a sharpie, and a jigsaw and you could make one.
OK, I just did my fuel rail gaskets this morning and did a test drive. Yesterday, I did the unscientific touch the fuel rail test and almost scalded my finger...could not hold on to the fuel rail longer than a second. Today after same intensity of driving, I could literally set my hand on it indefinitely. Those gaskets work really well. Also, it added more cooling to the aluminum manifold as I touched the metal at the throttle body connection, it was room temperature and not warm like before the fuel rail gaskets installation. As you predicted, little by little, things add up to a big difference.
Alone, each one of those gasket installations are a little improvement, but together they made an even bigger cooling effect over all.
I wonder if there is enough room in between the manifold bolt holes and the manifold bolts to be able to slip in a carbon fiber tube to help insulate the metal bolt from passing heat to the manifold bolt hole walls. Anyways, this shit worked so well, I am going to go back to the manifold bolts and add a phenolic washer in between the metal nut and the surface of the aluminum manifold bolt hole. I will do a before and after record to see if there is even more cooling after the washer is added to the phenolic manifold spacer I installed.
probably same easiness as the manifold spacer. Just cut the shape to match the TB and bore out stock sized TB o-ring and then install TB with its own original o-ring. I would be worried that the added phenolic thick spacer may give rise to fitment issues if the car happens to have any upgraded chargepipe fitting changes. I know this would definitely not work on my car since the charge pipe already jams up firmly against my expansion tanke.
But, also - this TB gasket won't be necessary imo because after installing the fuel rail phenolic spacers and the manifold spacers, the connection of the TB and the manifold was room temperature to the touch after an hr. of hard driving. So I don't think you can get it any cooler than room temperature. It was room temperature to the touch but felt 'cool' to the touch in contrast to the rest of the engine heat rising from below.
Ceramic oating the turbo manifolds, fuel rail and inlet manifold deflects and keeps heat in where needs it.
There is lots of room for improvement on these motors.
