Doesn't matter which way they go.
Only use copper coat on those gaskets. That's it. Or silver paint, but the copper coat is better.
You're taking a big chance. Those gaskets deal by trapping air in the raised channels. They were never designed to be used in bi-metal applications.
You can us them and maybe get lucky. You're better off getting the correct gaskets and machining the intake to fit. That's what I'd do.
