ARP SB Chevy w/18A Rollover Brodix 12pt head stud kit

If you're rebuilding the top end of your Small Block Chevy and using Brodix heads with the 18A rollover feature, this ARP head stud kit is what you need. These studs are designed to provide a more consistent clamping force than stock head bolts, which is crucial for sealing the cylinder head gasket under high compression and boost. ARP has been a go-to name for engine builders for a long time because they make well-built parts that hold up.

This kit uses 12-point nuts, which can be easier to access in tight engine bays compared to traditional hex nuts, especially when you're working with limited space around the cylinder heads. The studs themselves are made from ARP's proprietary 8740 chromoly steel, heat-treated to a tensile strength of 200,000 psi. This strong material ensures they can handle the significant cylinder pressures you'll encounter in performance applications, helping to prevent head lift and gasket failure. ARP includes a tube of their specialized assembly lube, which is important for proper torque readings and protecting the threads during installation.

When installing these studs, make sure to clean your block and head bolt holes thoroughly. ARP recommends using their assembly lube on the stud threads going into the block and on the threads of the nuts. This helps ensure you get accurate torque readings and makes future disassembly much easier. This kit is designed for a direct fit with the specified Brodix heads, simplifying your rebuild process.
