If you want to keep your 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. This will help keep your truck from popping head gaskets. These Gator Fasteners Performance Head Studs are heavy-duty studs designed for stock to moderately built Duramax engines.
