Hey Arizona,
I recently ordered a Mr. Gasket 260 from Summit and received the same gasket you did.
I contacted them about it, and they said that Mr. Gasket had gone out of business and they'd been having numerous issues with things being mislabeled.
I told them that the picture on their site was correct and they said they'd visually confirm that they had the right gasket.
I received a replacement and it was, again, the same wrong one.
Fortunately, they refunded me, but I eventually gave up and ordered a Remflex 3005 from Amazon.

FWIW, I'm using a generic int/exh gasket that came in a rebuild kit. I have been running it, with a set of hedman headers and an Offy DP, for 8 years without issue.
I would always use grade 8 studs with crimp nuts.

I've been really pleased with the Remflex, it seems to seal really well.
However, previously, I got an EFI intake/exhaust manifold gasket from O'Reilly.

It's a nice, solid, one piece gasket and it sealed really well.

Just order it from Amazon. Includes the riser gasket. Do you think the riser gasket would work for/with the heating plate/coolant?

The Mr. Gasket 260s I've received have a perforated separation where they fold in half, but they were still a single piece.
As for the riser gasket for the heating plate, I've had the same question and I don't think it's a good idea. The stock gasket is for exhaust whereas the heating plate will have coolant in it. It's designed to withstand high pressure and high heat, but not liquid. If it soaks through with coolant, it might weaken it/degrade it, who knows. (I'm only speculating).
You may be better off just using it as a template and making your own gasket out of gasket maker that's made for coolant. It's a pretty simple gasket shape.

I'm going to go both ways and thoroughly coat the riser gasket with Permatex Water Pump & Thermostat RTV Silicone Gasket Maker. That should do it! (I hope!)

Try taking a paper gasket you use for your thermostat housing and putting it between the head and the manifold and see how long it lasts.
There's a lot of different temperatures, pressures, agents (oil, exhaust, coolant, etc) that all have different properties. If there was a one-gasket-fits-all, that problem would have been solved a long time ago.

I don't know, you might be totally fine with it.
But, personally, I'd be concerned with the liquid permeating a gasket that's not designed to repel it. Maybe it'll get soggy and blow out? Dunno. I just know an exhaust gasket is designed for dry air and extremely high heat, not a moisture barrier.
Again, speculation, but I know intake/exhaust gaskets I've worked with are very different materials than coolant passage gaskets.
