| Viton Rear Seal |
| We also offer an upgraded VITON fluoroelastomer rear seal. Viton is made by Dupont, and has much greater resistance to high temperatures than standard rubber. It also doesn't have a tendency to dry out and shrink over time while sitting, which makes it a great choice for cars which will sit for months or weeks in between being driven. Overall, Viton is considered a top of the line material to use for rear seal applications. One more way to combat those pesky rear seal leaks. These fit all big blocks, all years. Our 144-1000 kit includes both upper and lower seal halves. |

| Silicone Rear Seal End Strips Kit |
| We also offer upgraded silicone rubber rear seal end strips. These are the small strips which fit down the sides of the rear seal cap and seal it to the block. These are a huge improvement over the standard style paper or cardboard strips. Silicone is considered a much better material to use for these rear seal end strip applications. One more way to combat those pesky rear seal leaks. These fit all big blocks, all years. Our 144-1001 kit includes a package of (2) end strips. Color may be orange or blue, depending on stock. |

| Stealth Cylinder Head Gasket (Qty 1) - Black |
| Our new "Stealth" cylinder head gaskets are a perfect match for our Stealth cylinder heads. They come teflon coated, which allows for a perfect seal on engines which have dissimilar metals, such as an iron engine block with aluminum heads. Because aluminum expands at a rate much greater than iron, these two surfaces move against each other as the engine heats up and cools down. The teflon allows for this movement, making sure there will not be any coolant or combustion leaks, even during extended street driving. We've fully tested these at up to 12:1 compression. These fit all big blocks, all years. They are sold individually (one single gasket,) so be sure to order two if you need a set. Compressed thickness on these head gaskets is .051" The Teflon coating is designed to be installed dry, so no chemicals or sealers are necessary for installation. Just clean your deck surfaces (we recommend using laquer thinner for this), bolt 'em on and go. Although these are designed for our aluminum Stealth heads, they also work great with other brands of aluminum heads such as Edelbrock, Trick Flow, ProMaxx, etc and you can even use them on factory iron heads also. |

Made from .015" thick gasket facing material, these are sold in a set of 4, and are designed to work with the factory replacement type valley pans listed on our gaskets section.

These interchange with Fel-Pro # 1216. These can also be used as standard intake gaskets with aftermarket style valley pans if the .015" material is preferred. |

| Permatex Silicone Ultra Grey 3.5 oz. |

We've tried practically every name brand and formulation of sealers out there on the market and nothing beats Ultra Grey. Use on oil pan/windage tray gaskets, timing cover, valve covers, water neck, water pump and housing, etc. Don't forget to throw one of these in when ordering gaskets. |

| Oil Pump Gasket |
| We now offer replacement oil pump gaskets. For some strange reason, these are not offered separately or included in ANY gasket sets from any of the major gasket suppliers such as Fel-pro, Victor, Rol, etc, and they are nearly impossible to find. Many of the gasket companies list "Oil Pump Gasket" in their catalogs, but under the description, the part is listed as an "o-ring", so it is actually the standard rubber o-ring which fits around the drive area of the pump, not the gasket. So, we've sourced these hard to find gaskets and now offer them for sale separately. Another "pain in the butt" big block Mopar problem made simple and inexpensive by 440 Source! |

They are just the ticket to repair those pesky rear seal leaks on all big block Mopar (361 383 400 413 426 and 440) engines. Sold as a pair (two halves which will equal one complete seal.) |

Another one of those super hard to find items that you really need for every quality build. Use two per engine, one on each side. |
