The Industrial Injection LB7 Duramax Stock Remanufactured Heads with Torque Lock Cups are designed to be an upgraded factory replacement. Complete ready to bolt on.

Heads are first jet washed in a high pressure spray cabinet to remove oil and dirt, then glass beaded to remove carbon. Next they are checked by magna fluxing, (cast iron only) or pressure testing. They are visually inspected for defects that would make them unusable.

New High Strength Alloy, Heat Treated iron based valve guides are installed. These guides are heat treated to Rockwell 22 Scale, which produces the ultimate in wear resistance. This is far superior to original guide material, including Bronze. The guide incorporates a spiral grove inside the guide to hold oil and aid the lubrication of the valve during engine operation.

Guides are then honed (not reamed) to exact size using a diamond honing mandrel. Diamond abrasives allow for consistency of size, surface finish, and bore geometry with no variation from guide to guide. The guide size is then verified using a valve guide bore gauge.

As needed the head receives new Premium valve seat inserts made from a true Nickel Based Non-Magnetic material that was developed for extreme operating conditions.

Next the head is treated to a multi angle valve job to help maximize the flow of air in and out of the head. This is accomplished using a Serdi 100 guide and seat machine. Serdi uses a solid carbide straight shank pilot. When inserted into the valve guide, it simulates the real valve stem during the centering process. This guarantees the valve seat is finished for a perfect valve to seat match.

Using CBN or Diamond tooling the head is given a new surface. With our Berco milling machine we can control the surface finish to accommodate different head gasket types. For example MLS head gaskets require a very smooth surface finish.

Finally the head is jet washed dried and assembled with new valve seals and new valve springs.

    Read Carefully!

    When you purchase a product from our website that has a core requirement, you have two options:

    1. You choose to pay the core charge and we will ship the product right away, then once we receive the cores you will be refunded the core charge if your cores pass our inspection qualifications. This is the preferred choice and has the least delays. 

    2. You choose to send in your cores before we ship the product that was purchased. This choice has the risk of delayed shipment of your purchased product and our inventory is not guaranteed by the time we receive your cores. You will need to follow all of the instructions below as quickly as possible so that you can get your purchased product and we can receive the cores. When you choose this option you acknowledge that by the time we receive your cores, our inventory could have change and there could be a delay in your shipment.
