ARP header bolts are available for 350-455 and LS Buicks in black oxide-coated chrome-moly steel or ARP’s own “Stainless 300” material. The bolts are rated up to 170,000 psi and the stainless versions are impervious to corrosion or extreme heat making them ideal for the application. The heads on the header bolts feature 12-points or hex head so they can be tightened easily in small increments.
