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.
Stainless Steel Shim Head Gasket- Package of 1 When you are trying to keep your compression as high as possible, there is no substitute for a steel shim head gasket. We've all used the factory Chrysler ones (before they were discontinued) and the current aftermarket ones, however, in order to save on cost, both of those are made from a cheap tin plated regular steel material. This leads to the number one killer of steel shim head gaskets: Corrosion around the cooling ports. Especially on cars which tend to sit for a long period of time without much use. So, to fix this issue, we've made our own steel shim gasket out of genuine STAINLESS STEEL to virtually eliminate all corrosion issues. And, not only is the material of much better quality than all the other options out there, but we've brought them to market at an even lower price than the competition! Another great option available only from 440 Source! These are supplied one per package, so order a quantity of 2 for one complete engine.
Copper Header Gasket - .064 Thick - Set of 2 We offer these solid copper exhaust gaskets. Copper works great for exhaust gaskets, as it's extremely heat resistant and the soft nature of copper conforms to any warping or irregularities of your headers or manifolds. We use .064" thick copper, which is thicker than other brands on the market. Sold in a pair (set of 2.) MADE IN USA!
