I use Permatex Ultra Copper sealant. Apply to the manifold side of the gasket only. Let it cure for 24 hours before starting the engine. This will help with the uneven surface on the manifold.

As for tools, I use a 9/16's box end wrench and a flex socket, the kind with the U-joint built in. You can do it with just the wrench. The worst bolt is the aft one next to the firewall, if someone has removed the stud and put in a bolt. The nuts by the carb aren't too hard, but it takes a lot of wrench turning due to the limited space.
