If you are wanting to keep your LP5 6.6L Duramax on the road for the long haul, you need to replace your head bolts with upgraded head studs.
These head studs have a much higher strength and will not stretch like the factory bolts will.
This will help keep your truck from popping head gaskets. These Thoroughbred Diesel Fasteners Performance Head Studs are a Heavy Duty stud designed for stock to moderately built Duramax engines.
