TSP Gen III Cylinder Head Bolt Kit, PAIR

These are the stock-replacement cylinder head bolts that are torque-to-yield and are built to the same specs as GM # 12498545.  They are the Gen-3 design that use three different bolt lengths and were used by GM from 1997 through mid-year 2004.  These cannot be reused after being torqued down because they stretch when torqued.
