If you are wanting to keep your LS Engine 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 Gator Fasteners Performance Head Studs are a Heavy Duty stud designed for stock to moderately built Duramax engines.
