BBC S/S Intake Bolt Kit - 6pt. 502

The BBC S/S Intake Bolt Kit - 6pt. 502 from ARP is the fastening solution serious big-block Chevy builders specify when maximum reliability and repeatability matter. Whether you're assembling a street performance engine, a weekend bracket racer, or a high-horsepower street machine, these stainless steel intake bolts eliminate the guesswork and failure points of factory hardware. Designed specifically for big-block Chevy intake manifold applications, this kit ensures precise clamping force and corrosion resistance that standard bolts simply cannot deliver.

ARP's 6-point intake bolt design provides superior grip and torque control compared to 12-point fasteners, reducing the risk of rounding during installation and allowing for consistent, reliable clamping loads across all bolt positions. The 502 specification indicates these fasteners meet ARP's premium standards for tensile strength and uniformity, critical for maintaining proper manifold sealing under varying heat cycles and boost conditions. Constructed from stainless steel, they resist corrosion from coolant, oil vapors, and atmospheric moisture, preserving clamp load integrity over thousands of engine hours. The precise manufacturing tolerances ensure that manifold gaskets seal properly and remain sealed, preventing costly coolant leaks that can compromise engine reliability.

This kit suits any builder working with big-block Chevy platforms—from 396 to 502 cubic-inch engines—where intake manifold clamping consistency directly impacts both cooling efficiency and gasket longevity. Mechanics and engine builders trust ARP fasteners because they eliminate variables that lead to re-work and warranty failures. Installation is straightforward with standard hand tools; simply remove the factory bolts and replace with this complete kit, torquing to manufacturer specifications for your specific manifold design. For any serious BBC engine assembly, this is the upgrade that pays for itself in peace of mind and reliability.
