If you are referring to the 1970-72 OAI models, the original plastic top has a round rubber gasket in the groove where the air cleaner body fits.
Aftermarket plastic tops have a rectangular rubber gasket in that location.
The factory provided springs that pulled the plastic top down toward the engine. The springs fit between holes in the side gussets that support the wide base for the sealing foam and brackets that attach to the valve cover bolt directly under those gussets. The springs and brackets are available from aftermarket suppliers. For example Fusick lists the springs as AFS70 for $5.50 ea. and the brackets as SHD83 for $9 each.
If the springs are in place, the plastic top should not rotate, even without a gasket.

I see you don't have the breathers on both sides of the adapter. That's OK. but you need a breather, tube, and connection to the OAI adapter on the other valve cover. That, and the springs, will prevent the adapter from rotating.
My OAI adapter does not rotate, even though I discarded the gasket to get extra hood clearance.
