    Product Description

    LS 2004+ LS Head Bolt Kit LS2 LS3 LS6 LQ4 LQ9 LY5 LY6 LM7 4.8 5.3 5.7 6.0 6.2 7.0

    Be sure to note which head bolts you need as GM used two different style LS head bolts

     1997-2003 engines used QTY 8 155mm Bolts, QTY 2 100mm bolts, and QTY 5 45mm bolts

    Mid 2004-2014 engines used QTY 10 100mm bolts, and QTY 5 45mm bolts

    For model year 2004 blocks, you will need to verify whether the block is an early or late design. If 8 of the 10 larger head bolts on each side of the engine are longer and 2 are shorter, you will need the 2003-earlier style bolts. If all 10 bolts are the same length, you will use the 2004-later style bolts. 

     Choose the option for enough fasteners for one or both cylinder heads. 

     These cannot be reused after being torqued down because they stretch when torqued
