PAIR of Brian Tooley Racing (BTR) LS Cylinder Head Bolt Kits for 1997-2003 LS1/LS6/4.8L/5.3L/5.7L/6.0L - BTR98545 Like GM#12498545
This listing is for two sets of head bolts, one for each cylinder head.
These are OE style torque to yield cylinder head bolts and are a direct replacement for 1997-2003 LS platforms.
NOTE: These are for LS applications only and do not fit LT engines. 2004 was a split model year and may have either head bolt style. Please be sure to verify that your engine requires the head bolt kit that features three different sizes of bolts per cylinder head (2004+ used two different sizes of bolts per cylinder head).
