MS98002T is the Fel-Pro number for the steel backed gasket set. Doing this intake is pretty easy. If it comes down to it, I would only use the steel backed set, not the plastic set.
Tip: If you're going to do the job, an easy(er) way to remove it is to leave as much attached to the intake as possible. Leave the up half attached, leave the fuel lines attached to the upper. The ones that I've done have had a second fuel connection at the back of the intake. Take the lines loose there and remove the support bracket bolt from the bellhousing. You should only have to remove the coolant hoses and wire harness. You will have to remove the accessory drive bracket (a cast aluminum piece) to make room for the intake's removal and installation. It also partially obscures a manifold bolt.
