SBC LS-RHS BLK W/RHS LS7 Cylinder Head Stud Kit – 234-4339

ARP SBC LS-RHS Block with RHS LS7 Cylinder Head Stud Kit

Upgrade your GM LS-series engine build with this ARP cylinder head stud kit, designed for applications using an RHS LS block with RHS LS7 cylinder heads. Built from premium chromoly steel and finished in black oxide, this head stud kit provides the clamping strength and fastener reliability needed for high-performance street, race, boosted, and naturally aspirated LS combinations.

ARP head studs are a preferred upgrade over standard head bolts because they help provide more consistent cylinder head clamping force, improved gasket sealing, and increased strength during high cylinder pressure operation. This kit includes 12-point nuts for a professional installation and improved wrench access in tight engine bay or cylinder head areas.
