Which Felpro Valve Cover gasket?

[Driftwood]

For 350 SB they have a few different cork ones, a rubber one, and a PermaDry Plus one. I think the PermaDry is the same material as the 1 piece oil pan gasket I just installed, which I really liked. It's the most expensive so I assume it's the best one. Any opinions? Also do you use gasket tack or anything when installing this gasket?

Thanks,
Andy
