Medina, a 1971 T-code Monaco

Dave and Steve, is the gasket below what you have used successfully? The picture is from an eBay vendor but, were I to get a set, I would prefer to buy from a "mainstream" vendor if possible (no reason to doubt this specific eBay seller, but I'd rather go with a brick-and-mortar store or an online store like Rock Auto).
I have found two threads on this topic. One is here, in which @cbarge shares his good experience with the product. In the other here, @Big_John mentioned that even the heat-resistant ones fail after a few years -- has anyone had the same experience? The picture John used is the same as the one below.

Over a lunch break, I found that the Fel-Pro MS90425 (exhaust Manifold gasket set with heat shield) IS in fact listed on the usual websites (Autozone, O'Reilly, Summit) yet it does not pop up when I specify that I want it for a 1971 T-code engine: that is because the part is listed as appropriate for a 440 from 1974 onward.
Fel-Pro itself specifies 1974 on. Does anyone see any reason to not use it on a 1971 T-code engine?
@cbarge, @Dana, @saforwardlook -- can you confirm where you got yours?

My exhaust manifold gaskets came in a Felpro engine rebuild set I got from Autozone for a 1971 Chrysler. They look a little different than the ones above, but either ones should work. I can't say there is a good solution to this problem since I haven't put enough continuous miles on my cars with them to judge that verdict. I did reason that a gasket might help prevent the exhaust manifolds from warping because the manifolds and the heads are not in direct contact with each other, rather they are insulated by the gasket, which would likely reduce warpage of the manifolds potentially.
My gaskets are a foil type covering on one side and the other side is an insulating fiber material it appears. I am not certain which side goes where, but I believe the fiber side would go against the head and the foil side against the hotter exhaust manifolds. Maybe someone has a better thought?

Foil side faces out. Clean head and manifold surfaces, heavily pitted manifold surfaces will need to be brazed and machined.
Tea time. Couple of items to tie loose ends:
1. Attached is a photo of the compression test results -- Medina's engine passed with flying colors before getting repainted. Note that @71Polara383' gauge works in 5-unit increments, which explains the notable consistency of the results across all eight cylinders -- well above 140 psi in all cases.
2. As illustrated in p.9 of the present thread, Medina's engine has just been repainted using (almost 3 cans of) Bill Hirsch Chrysler Blue. A thorough discussion of what led me to make this paint choice, and of several alternative paints that I ended up not using, can be found in this other thread.
3. While we were at it, I bought a new oil pressure switch light (NAPA Echlin Ignition OP6282). Here is a picture after installation.
4. Finally, we replaced the Schumacher Poly-Locs with the Mity Mounts. My hope is for a nice, smooth engine bay.

Well, with the engine all cleaned up and prettified, @71Polara383 convinced me that the engine bay should be cleaned up. That was the job for Saturday!
As you can see, the engine bay is much cleaner than before. In particular, the goopy residue from the failing voltage regulator that Wyatt replaced in early 2019 are now gone.
Visible in the cleaned up bay is the original power booster that I had rebuilt by Booster Dewey and Booster Steve.
PS: to speed up the job, I bought a pressure washer. The Subaru-engine model that @sixpkrt had kindly recommended to me was out of stock locally, so I went with a Ryobi 3000 with Honda engine -- which was in stock at he Home Depot in Rockford. Bit more expensive, so make sure to buy it when it's on sale (13% off last week). Here are pics in Wyatt’s ServPro and put together at the shop.

i do heat stuff before painting. takes the oils and moisture out.
Nope, she's GY9 Dark Gold ("Tawny Gold" over at Chrysler/Plymouth/Imperial) who was repainted in burgundy by the previous owner.
In other words, she's a blonde who's had her hair dyed red
The above pictures of the Mity Mounts did not yet show the Fel-Pro manifold gaskets with heat shields that have since been installed: two close-up photos of Medina's are here. Here are two other shots:
The heater hoses were still the OEM ones: out of an abundance of caution, they have been replaced by new ones (a local store had a big sale, which is nice, and Wyatt cut them to length).
Here are a few pictures showing Medina's engine after their replacement, and with components put back on.

The previous owner described her original color as "green", which I can see as a correct description of GY9 in the shade and especially in the rain. In the sun, as the above photo shows, it really is dark (OK, OK, brownish) gold. Here is a photo of a GY9 A-body with its original paint in the sun, sporting a white vinyl top like Medina:

It depends on the light. In my garage under flourescent lighting it appears quite brown.
