Step One : Find a friend or two.

Step Two : Convince them to help you.

Step Three : Get a decent intake gasket set with rubber end seals.

Step Four : (this is where the friends come into play) When you pull the intake, lift it straight up. A FE cast iron intake weighs slightly less than a battleship anchor.

Step Five : When replacing the gaskets, put a nice little daub of silicone where the end gaskets tab into the intake port gaskets.

Step Six : Make sure the intake gets set in straight down on the gaskets withoout having to "wiggle" the intake into place.

Step Seven : Buy your friends beer for being good buddies.
