It is for good reason that virtually every top professional engine builder relies on ARP Head Studs for their all-out competition LS powerplants!
Simply stated, there's not a better stud setup on the market today.
Made from premium grade 8740 alloy and propriety ARP2000 alloy that are rated far superior to "air craft" quality alloy steels.
Providing a more accurate and consistent torque loading over head bolts, they are available for both LS1 Staggered length bolt blocks and the later LS2/3/6 same length style blocks.
