Dura-Bond 30000 Series valve seat inserts are the most machinable of the Dura-Bond valve seat materials. The sintered valve seat insert offers a blend of finely dispersed tungsten carbide, residing in a matrix of tempered tool steel and special alloy iron particles. The superior machinability is the result of adding proprietary ingredients and solid dry lubricants to this blend—and by using a special processing technique during manufacturing. As a result, these are much easier on cutting tools and won't have the typical chunks of carbide. Go with the easy-to-cut, yet extremely strong Dura-Bond 30000 Series valve seat inserts for your next engine rebuild.

Dura-Bond 70000 Series valve seat inserts feature sintered, high-speed (tungsten carbide) tool steel construction. Special additives blended into the matrix impart high-temperature lubrication properties which makes the material impervious to extreme heat and machining, enabling it to be used in "dry" fuel applications such as propane (LPG) and natural gas. Dura-Bond 70000 Series valve seat inserts are more than adequate to withstand the demands of modern engines that put a higher level of thermal and mechanical stress on valve seat inserts. The patented materials and processes offer excellent machinability, along with low wear and high heat resistance. For the heavy- or extreme-duty use Dura-Bond recommends their 70000 Series valve inserts and are used in engines using diesel, unleaded gasoline, and propane.

Once you see Trick Flow® PowerPort® 240 heads for big block Mopar in action, you'll agree they are the only aftermarket aluminum heads worth using on your engine! What makes PowerPort® 240 heads so great? For starters, they're made from premium grade A356-T61 aluminum. That's important because it weighs a lot less than cast iron and is very strong.
