If you are wanting to keep your 6.0L Power Stroke on the road, 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. The Gator Fasteners Performance Head Studs are a Heavy Duty stud designed for stock to moderately built 6.0L Power Stroke engines.
