EARL'S / HOLLEY TBS-004ERL Features:
Earl's Racing Products head bolts are made from premium quality 170,000 psi chrome moly alloy steel (about 15% stronger than Grade 8). These bolts have a reduced wrench size (choose from 12-point or hex head) for extra socket clearance (provides extra clearance to rocker arms when re-torqueing heads).
