I've seen people use all kinds of weird stuff to try to seal those. I've also seen oil leak into the seating channel for the valve cover and leak up and out over the top of the gasket when people "glue" the valve cover to the head.
The gasket leaks when, for one reason or another, the "pushing" force of the rubber gaskets is so longer enough to provide enough sealing force to resist the crankcase pressure. If gaskets are failing prematurely, I would be investigating the CCV system, not trying to modify the gasket to be "glued" to the head.

This is with engine idling. I've removed ccv system completely, and the hose from valve cover goes into the manifold.
I've done it more so to help with oil consumption, as many suggested. So I think it created less pressure and more vacuum. In my case it didn't help with oil consumption. Soaking cylinders with Acdelco stuff didn't help either. The only think that stopped oil consumption was Lucas honey stuff.
Now I don't know if whatever pressure/vacuum I have under the valve cover is making matters worse or better.
I was under the impression that I have pretty light vacuum, which would not be causing the gasket to leak.
As far as form a gasket is concerned, it seems that it's made exactly for this purpose. I dont know why you call it weird. It literally says to be used on gaskets
