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.
If you are using our Stealth aluminum cylinder heads, these brand new head bolts are just the ticket. Featuring very high strength, but still at a great price, these are the way to go. Priced at a fraction of the cost of the name brand bolts, these are custom made for us by one of the largest bolt manufacturers around. They feature reduced diameter 12 point heads for easy access in applications that have countersunk head bolts (such as our Stealth aluminum heads or Edelbrock Performer RPM heads), but they also work great with factory iron heads. Rated at 170,000 PSI, they are far stronger that the factory head bolts, or even a standard type grade 8 bolt. We even include .100" thick hardened washers with them. One set contains enough bolts for two heads (one complete engine.)
Trick Flow 240 and 270 heads have larger intake ports, which raises up the top of the head. A taller head requires longer than stock head bolts. These reduced diameter USA made bolts feature 12 point heads, and are rated at least 170,000 PSI, far stronger than the factory head bolts or even a standard type grade 8 bolt. We even include .100" thick custom made hardened washers with them. One set contains enough bolts for two heads (one complete engine.) A great USA made choice, strong enough for virtually all applications, at a price that won't break the bank! For use with Trick Flow Heads ONLY! Exact appearance may differ slightly from the photo.
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.

This valley pan is the same as our single plain models, except it features a clearance well which will clear the exhaust crossover found in the Edelbrock Performer RPM intake manifold. It DOES NOT work with stock cast iron intakes, the Edelbrock standard Performer, or any others. These also work well with our aluminum Stealth heads, Edelbrock RPM heads, 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. It 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.

This version fits the "B" (361/383/400) engines.
Our exhaust stud kit includes the original factory length exhaust studs that came on Mopar big blocks from the factory. These are great for restorations, or for cars with headers. These studs allow you to hang the headers from the studs during installation, making things easier. Works with factory iron heads, as well as aftermarket aluminum heads. Includes 6 per package, enough to do one head, so order two packages for a complete engine.
We now offer a kit to replace the freeze plugs in factory iron big block Mopar heads. These are made from brass, which offers a big upgrade in corrosion resistance from the factory steel plugs. This kit includes four large and four small plugs, enough to do one complete engine (two cylinder heads.) Fits all 1963 and later big block Mopar applications, such as cylinder head casting numbers:

2951250
3462346

Our Performance 12 point bolt kits are a nice looking option that features grade 8 strength, black oxide coating, and with a price that doesn't break the bank. This kit includes all 12 bolts you need to attach the valve covers to the cylinder heads. This is our "SHORT" (3/4" length) bolt kit which works great with valve covers that have a thinner flange such as most chrome stamped steel or factory type covers or fabricated covers that use a flange that is 1/4" or thinner. Custom matching, small diameter washers are also included with this kit.

This is a labor charge for us to remove and replace valve springs, seals, locks and retainers. This labor charge must be selected in the same order as the cylinder heads, along with the new valve locks, retainers, seals and springs you want upgraded. Does not include custom shimming each spring to a specific installed height.
