BBC S/S Head Bolt Kit 6pt.

The ARP 435-3601 Big Block Chevy Stainless Steel Head Bolt Kit with 6-point fasteners is purpose-built for engine builders and mechanics who demand reliability under extreme cylinder head pressures. Big Block Chevy engines generate tremendous combustion loads, and factory head bolts often fall short when boost, nitrous, or high compression ratios enter the equation. This kit replaces those weak links with ARP's proven fastener engineering, delivering the clamping force and fatigue resistance needed for street, strip, and race applications.

ARP's stainless steel construction resists corrosion and maintains tensile strength across temperature extremes—critical when engine bays see repeated heat cycles and coolant exposure. The 6-point socket design eliminates rounding issues common with 12-point fasteners, ensuring precise torque application and repeatability across multiple rebuilds. These bolts are manufactured to ARP's strict tolerances and metallurgical standards, with each fastener engineered to maintain proper clamp load without stress relaxation. The stainless material also reduces galling during installation, a significant advantage when working on iron or aluminum cylinder heads.

Whether you're assembling a street 454, a modified BBC drag engine, or a marine powerplant, the ARP 435-3601 kit ensures consistent head gasket sealing and eliminates the risk of head lift at peak boost or high RPM. Professional engine shops and serious enthusiasts trust ARP fasteners for their dependability and longevity. Proper torque specifications and ARP's included installation instructions are essential for optimal performance. This is a direct replacement for factory Big Block Chevy head bolts and fits all standard BBC cylinder head applications.
