Steel (OE Style) Valley Pan Intake Gasket
These are a steel valley-pan style gasket with no gasket material. They are intended to be installed using brush-on gasket sealer (sold separately) on both sides of the portion of the gasket that goes between the head and intake. If you prefer, you can substitute a bead of silicone in place of the factory rubber end seals, to seal the front and back of the pan to the block (bottom of the pan). Be sure to get silicone under the corner of the head at each end of these seals (whether you are using the rubber seals or a bead of silicone). Do NOT use silicone or any other method to seal the top of the pan to the bottom of the intake across the front and back – this is intended to be left unsealed, and sealing it often causes vacuum and / or oil leaks. If yours is damaged, or going to be unreasonable to clean for re-use, we do sell them separately.
Our composite intake gaskets block the exhaust crossover by default, which is worth a little power, but can be opened up for applications needing a functional exhaust crossover (such as for EGR or divorced choke functionality on a stock intake, or cold weather driving with a stock, Edelbrock, or PC3 intake). We recommend the composite intake gaskets for _all_ applications using an aluminum intake or heads, as this gasket does not always play nice with the aluminum, when exposed to moisture (including humidity), and can result in bi-metallic corrosion that will eventually cause a vacuum leak. In the desert, our testing has shown that it takes more than 10 years for that to become a problem, but in the mid-west, it can often be less than half a year. Reports from customers on the coasts indicate that environment may cause failure in less than a month in certain conditions.
