ARP SB Chevy 18A std port head bolt kit

These ARP head bolts are made from forged 8740 chromoly steel, a strong material that holds up well under the stress of engine operation. They're designed for standard port Small Block Chevy cylinder heads, ensuring a good seal when you're rebuilding or upgrading your engine's top end. The kit includes hardened parallel ground washers, which help distribute the clamping load evenly across the cylinder head surface, preventing damage and ensuring a consistent torque reading.

ARP is known for making well-built fasteners, and these head bolts are no exception. They are rated at 180,000 psi tensile strength, meaning they can handle significant pressure without stretching or failing. This makes them a solid choice for many engine builds where reliability is key. The kit comes with everything you need to get the job done, including the bolts and washers.
