Buick V6 Stock GN1 Champion Head Bolt Kit

ARP 223-3705 Cylinder Head Bolt set
Fits 1986-1987, Buick V6 with GN1 Champion heads

ARP's Professional Series head bolts deliver superior strength and meet the ARP "Zero Defect, Zero Failure" quality standard. They are cold-forged for molecular integrity, then heat treated prior to machining and thread rolling, and are rated at 200,000 psi. These bolts are application specific and designed to be primarily used in racing applications. Most sets have undercut short bolts to help eliminate head gasket failures by providing more "stretch" which compensates for the additional compression of the head gasket. All "Professional Series" head bolts have a reduced hex size and a wide flange to eliminate the need for valve train removal to re-torque the cylinder heads and also to allow the use of larger diameter valve springs.
