Required for our New Small Six (170/200/250ci) Aluminum Cylinder Head, this kits only includes the 7 longer studs that are needed to install the new head. Use 7 of your existing studs, the washers and nuts. 
 
ARP® studs and bolts are substantially stronger than OEM fasteners. For most applications studs are recommended, as the use of studs makes it much easier to assembly an engine, with the cylinder head and gasket assured of proper alignment. More importantly, studs provide more accurate and consistent torque loading, assisting in the prevention of cylinder head gaskets leaks.

For more information on ARP Bolts and Studs, and why Studs are recommended, please read our ARP Tech Article. It also includes tips for installing ARP Bolts and Studs, as well as the recommended torque specs.

CAUTION: When installing cylinder head studs on the small six, you need to make sure the front head stud, on the exhaust side of the motor, does not project deep enough as to interfere with the water pump impeller. This must be verify prior to starting the motor, as failure to do so may damage the water pump impeller or internal engine parts, possibly resulting in catastrophic engine failure. If the stud is to long, simply remove the stud and grind off the excess. This stud is also a wet stud (in contact with engine coolant), therefore you must use ARP thread sealer (or equivalent) to prevent leakage or rust, which may make future stud removal difficult.
