HEAD PARTS KITS - LS

Dart parts kits include everything needed to assemble a cylinder head: stainless steel valves, springs, locks, retainers, seals, studs, and guideplates. These kits contain the same high-quality components Dart uses in their cylinder head assemblies. Dart Machinery has been a leader in race-winning components since 1981, developing and manufacturing products in-house. They use premium materials like 355-T6 aluminum (50 degrees more heat resistance, 5,000 psi more tensile strength than 356 alloy). Advanced casting technology allows for higher density and strength in combustion chambers, and tighter casting tolerances for profiled valve guide bosses and smoother surfaces for improved flow. Dart integrates continuous improvements from Pro-Stock campaigns and interactions with racers. Dart blocks and cylinder heads offer exceptional value and out-of-the-box performance, with features not found in factory castings.
