This 21 piece set includes 7 long studs, 7 washers & nuts - fits 200/250ci engines with Classic Inline or Vintage Inline aluminum cylinder head
Required : for the New Small Six (170/200/250ci) Aluminum Cylinder Head, this 42 piece set includes the studs, 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.
Torque Spec's 80 ft/lbs with ARP Lube
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.
