Valley Pans & Hold-Down Bars-store.440source.com

ACCOUNT INFO

This page covers "valley pans" which are sometimes referred to as "bathtub gaskets." It's the piece of sheet metal or stamped steel which fits below the intake manifold and seals off the lifter valley. We carry several different types, from the original stock replacement versions, to slick aftermarket fabricated sheet metal versions for use with aftermarket aluminum heads. We also carry the accessories which hold the valley pan on, such as the "holddown bars" and the bolts. It's important to note that "B" (low deck) and "RB" (tall deck) engines both use different widths of both valley pans and holddown bars. Since the "RB" engine's deck is raised, this increases the distance between the heads, making it necessary to use a different intake manifold, valley pan gasket, and holddown bars.

Stainless One Piece Valley Tray - For "RB" Engines
Our one piece stainless valley trays look and fit great! Made 100% here in the USA from genuine 22 gauge 304 stainess steel sheet, these feature standard (non Max Wedge) port size, and they work best with single plane intakes which do not have the heat crossover under them. If you want to use these with a dual plane intake, you would have to mill off the heat crossover on the bottom of the intake manifold. This version fits "RB" (413/426/440) engines. Don't forget to order intake gaskets and valley pan hold down bars and bolts to go along with these, if you need them.

Sheet Metal Valley Pan - RB Engine - Single Plane
Our fabricated sheet metal valley pans work great with our aluminum Stealth heads, Edelbrock RPM heads, Trick Flow 240's AND 270's, or any other aftermarket heads which feature an unbroken deck surface where the lower edge of the head's deck surface meets the edge of the valley pan. They will also work with factory cylinder heads, however there may be a small gap where the lower deck surface has a break which may need to be filled with silicone, depending on the intake manifold you are using. The pan is shown upside down in the picture. When it is installed, the "lips" along the long sides will fit underneath the edge of the cylinder heads, making a tight seal and allowing the use of standard intake port gaskets. This pan is designed to work with SINGLE PLAIN INTAKES only. Dual plane intakes (including stock units) will not fit due to the exhaust crossover which hangs down underneath them. We do have some other models which may work if you are using a dual plane intake Because this pan is a single solid piece which fits "under" the cylinder head intake face edges, it requires at least one cylinder head to be off during installation or removal. Supplied in a gold irridite finish for good looks and corrosion resistance. We carry these in two different versions, one for the "RB" (413/426/440) engines and one for the "B" (361/383/400) engines. Be sure to select the correct one for the type of engine you are working on.
