Description

The ARP 480-1101 is a set of 14 stainless steel header bolts with a hex head. These bolts feature a polished finish and have a 3/8 in.-16 thread size. They are designed for Oldsmobile V8 engines with displacements ranging from 330 to 455 cubic inches.

These header bolts are 15 percent stronger than Grade 8 steel and offer high corrosion and heat resistance. They have a compact head design to fit into tight spaces next to headers. ARP recommends using anti-seize on all stainless steel fasteners.
