Well, technically none of them require milling. However, modern gaskets are thicker than the original steel shim gaskets. The compression ratio will be raised slightly, but if you are just doing a stock rebuild I would not worry about it. You won't be able to tell a difference.
Mike (Azcoupe, who owns Classic Inlines) is in talks with Cometic to get thin MLS gaskets made, but that is in the future. The best gasket available now is the venerable Fel-Pro available everywhere.
