LS 1/2" Head Stud Kit

Head gasket sealing has been a consistent issue with LS engines trying to make big power. The most sure fire way to combat the problem is upgrading to 1/2” head studs with this kit. Kit includes the necessary studs and nuts, it does not include the mounting location above the lifters. The 6 bolt kit (LSX, Dart or ERL blocks) includes 1/2” hardware for the primary clamping points and 3/8” for the added points. *NOTE* Each kit requires machine work to the cylinder block and heads (6 bolt kit pictured)
