Eliminate the hassle and cost of replacing OE torque-to-yield style bolts each time the cylinder heads are removed by upgrading to reusable Chromemoly steel bolts from Earl's.
Earl's Head Bolts are manufactured from 170,000 psi yield strength Chromemoly alloy steel and are up to 15% stronger than traditional grade 8 bolts. Each bolt has a reduced wrench size, for extra socket clearance as well as a widened flanged head to provide additional support for thicker washers. All Earl's Head Bolts are black oxide coated for long-lasting durability and are sold in complete engine sets to provide all the hardware needed for an engine performance upgrade.
