This GM Cylinder Head Bolt Kit for 97-03 LS1 or LS6 does one bank only, so two sets are required for one engine.
These engines use torque-to-yield bolts, so head bolts cannot be reused.
Gen III LSx engines produced from January 2004 forward have a short style head bolt design, so these earlier head bolts WILL NOT fit. Use GM #17800568 for engines produced from January 2004 and later.
