Intake sealing and blocking the heat crossover

It looks like this is the Mopar gasket set that comes with the block off plates. Has anyone used it? Are these good quality gaskets? Might be the way to go for me if so:

Here's the Fel-Pro printoseal gasket set and it's steel core. If I just add a thin stainless steel shim stock to this gasket I assume the steel core + the added piece of shim stock would do very well to hold up to keeping the port blocked?

Any additional input is appreciated. I really only want to do this once.

Stock port on cast head is fractionally smaller than cutout in pan gasket. Effectively intake manifold keeps it in place by pressing it onto head. I cut it butt fit into cavity, then epoxied with Pratley epoxy.

That just sounds risky to me. If that epoxy ever burns off that block off plate you made will fall in. I don't want to risk that.
