    • ​Recommended over the MAHLE Head Bolts, these are a superior replacement for the head bolts and are rated at 220,000 psi tensile strength.

 

Tech tip: Installing head gaskets on your Duramax is very technical and labor intensive. You should have strong mechanical skills to complete this job, 30-35 hours should be allocated. It is highly recommended to add an ARP head stud kit. Other repairs such as water pump and injectors should be considered since you will have easy access at this time. We use and recommend OE Manufacturer C series gasket because it is the thickest of the 3 available. Valve adjustments are not always necessary but should be checked.

DmaxStore Note: This is also a good time to replace your glow plugs. The glow plugs may need replacement due to coolant contamination. If your glow plugs haven't been replaced recently, there is a slim chance they make break off in the cylinder head during removal. It is much easier to extract a broken glow plug with the cylinder heads off.
