Brand: Automotive Racing Products (ARP)

High-performance ARP Pro Series Head Bolts are rated to 190,000 psi for exceptional strength in the most demanding applications. The flanged head and reduced hex size on these bolts offer easier access for retorquing without removing the valve train.

This full kit includes all of the cylinder head fasteners required to complete one engine: 10 small (M8x1.25, 10mm head) bolts; 4 short (M11x2.0, 13mm head) bolts; 16 long (M11x2.0mm, 13mm head) bolts; 30 hardened, parallel-ground washers; a packet of ARP assembly lubricant; and full instructions. All hardware in this kit is 8740 chrome-moly steel with a durable black oxide finish.

Fits Gen III LS-Series small block Chevy (2003 and earlier) that use two different lengths of M11 head bolts. This includes LS1 and LS6 5.7L and 6.8L V8 engines. Not for 2004 or later engines which use all one length M11 bolts.
