05-13 LS2 / LS3 / LS7 ARP Head Bolts (ND)

For those who prefer head bolts to studs ARP manufactures premium quality "Pro Series" head bolts that are nominally rated at 200,000 psi tensile strength and have 12-point head with wide flanges to more evenly distribute the load. Far superior to factory TTY bolts (which are preloaded to yield and cannot be reused). Earlier LS engines have unequal length head bolts and for 2004-up they're equal length.
