My motor is smoking!

Like Dodgefreak said the steel shim gaskets were designed for cast intakes but you can use them if you seal them with High Tack or a similar shelaq (sp?) but fel-pro's or other good composition gaskets work better and don't require sealer around the ports. In fact if you use sealer on some of the composition gaskets they don't seal as well. Also never use RTV on an intake port because it turns to jelly when gas hits it. It's great for the end gaskets but not the ports.
