Product Description
Manufacturer Part Number: 134-3610
Cylinder Head Bolt Set; For Use With 2004 and Later Gen III/ LS Series Small Block; 12 Point Head Type; 200000 Pounds Per Square Inch Tensile Strength; Black Oxide; Chrome Moly; With Washers
All Pro Series bolts are cold forged to ensure molecular integrity, heat treated prior to thread rolling and machining, and are rated at 200,000 PSI tensile strength. ARP Pro Series head bolt kits are application specific, designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP "zero defect - zero failure" quality standard. Hardened and parallel ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12 point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more "stretch" to compensate for the additional compression of gaskets.

I rarely leave a review, but in this case I feel it is necessary. Over the last 20 years of building engines, I have and always will use ARP fasteners. They have been the only manufacturer I turn to for all our builds. Today, I had the first failure. A head bolt sheared off in the block. What was an almost complete build, is now back to parade rest. We always use ARP's guidance for install, and never go beyond the tried and true specs. We are assuming the failure to be a material issue. Just a reminder that even though they are the go to source, nothing is guaranteed in this business. Hopefully, the machine shop can remove the broken bolt. If not, it's a wasted LS block.
