Dart Cylinder Head Stud and Bolt Kit

The Dart Cylinder Head Stud and Bolt Kits are designed specifically for use with your Dart heads, ensuring a secure and trouble-free installation. Exact tolerances ensure that gaskets and cylinder heads just glide into position and align perfectly. These kits are manufactured from premium 8740 chrome moly steel and heat treated to 190,000 psi. They are thread rolled after the heat treating process, which vastly improves their fatigue tolerance compared to studs threaded before heat treatment. High-quality, parallel ground washers included!
