This head bolt set is engineered for 370, 429, and 460 cubic inch V8 engines, covering 6.1L, 7.0L, and 7.5L displacements used across trucks, vans, and passenger vehicles from 1968 to 1999. Whether you're rebuilding a heavy-duty truck engine or restoring a vintage platform, this kit ensures secure, factory-level performance. Manufactured from hardened steel, these bolts provide high clamping force and long-lasting reliability under high-load conditions.
