Bolt Set, Header, ARP, Buick 350-455 3/8" Thread Size, 0.750" UHL, 14pc

Available in black oxide or stainless steel

ARP header bolts and studs are available for 350-455 Buicks in black-oxide coated chromoly steel or ARP’s own Stainless 300 material. Both the bolts and studs are rated up to 170,000 PSI and the stainless versions of both are impervious to corrosion or extreme heat, making them ideal for the application. All the studs come with a special starter nose nut to prevent cross threading. The nuts for the header studs, and the heads on the header bolts, feature 6 and 12-point heads, so they can be tightened easily in small increments.
