Main Stud Kit for 200ci motors with 7 mains. The 42 piece set includes washers and nuts. 

ARP® Bolts and Studs are approximately ten times stronger than OEM fasteners. For most performance applications, studs are recommended over bolts. Studs make it much easier to assembly an engine, assuring the cylinder head and gasket are properly aligned. Studs also provide more accurate and consistent torque loading, which aids the prevention of cylinder head gasket leaks.
