When you upgrade the performance of your Olds engine, many times you will exceed the capabilities of the factory hardware. ARP has the solution for you. Made out of premium grade 8740 chromoly, these head bolts have a strength rated far superior to OE and "aircraft" quality bolts. This material is heat treated to provide a tensile strength in the 200,000 psi range and is an excellent choice for building your high revving all motor, or forced Induction application.
