Intake Manifold Facing Gaskets with Silicone Seal - Set of 4

Our new .025" thick intake facing gaskets are made from a high quality composition fiber material and feature a pre-printed silicone bead around the ports. These are designed to be used with a factory type "bathtub" steel valley pans. These are supplied as a set of 4 gaskets. 2 of the gaskets go on top of valley pan (between the pan and the intake manifold) and the other two go underneath the valley pan (between the pan and the cylinder head face.) They can be used "as-is" for standard (non Max Wedge) applications which are 2.375" tall by 1.280" wide, or you can open up the top of the port area slightly, which will convert them to 2.650" tall ports, for Max Wedge or other ported head applications.
